Solve For X. Helppp!
Answer:
x = 64
Step-by-step explanation:
The 3 angles on the right lie on a straight line and sum to 180° , that is
90 + x + 26 = 180
x + 116 = 180 ( subtract 116 from both sides )
x = 64
Answer:
64
Step-by-step explanation:
You have to do 90 - 26, which will then give you the answer 64
Double check it: 26 + 64 = 90.

Step-by-step explanation:
Answer:
4 is your answer
Step-by-step explanation:
Please help! For math.
Answer:
Soln:
x=64(vertically opposite angle)
x=64
Now,
y=18(vertically opposite angle)
y=18
Again,
y+z+x=180(being straight angle)
or,18+z+64=180
or,82+z=180
or,z=180-82
orz=98
Hence the value of x=64, y=18and z=98.

Someone answer this please
Answer:
The answer is -72/5.... also as 14.4
Answer:
Step-by-step explanation: first put in the value for x, 8(-6) -5y=24
Then solve from there, 8x-6= -48
-48-5y=24
-5y=24+48 ( becomes pos when transferred to this side, since it turns to the opposite direction )
Now, -5y=72
Decide both sides by -5 and then
Y = -14.4 or -14 2/5
A spinner is divided into five colored sections that are not of equal size: red, blue, green, yellow, and purple. The spinner is spun several times, and the results are recorded below:
Spinner Results
Color Frequency
Red 7
Blue 15
Green 6
Yellow 5
Purple 8
Based on these results, express the probability that the next spin will land on purple as a decimal to the nearest hundredth.
Answer:
The probability that the next spin will land on blue is 0.12.Step-by-step explanation:
The result of the several spins are as follows:
Color Frequency
Red 18
Blue 9
Green 18
Yellow 19
Purple 12
TOTAL 76
Compute the probability that the next spin will land on blue as follows:
Thus, the probability that the next spin will land on blue is 0.12.
A certain television is advertised as a 21-inch TV (the diagonal length). If the height of the TV is 13 inches, how wide is the TV? Round to the nearest tenth of an inch.
Answer:

Step-by-step explanation:
The width of the TV will be equal to 16.49 inches.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides.
Given that a certain television is advertised as a 21-inch TV (the diagonal length). If the height of the TV is 13 inches.
The width of the TV will be calculated as,
W = √ ( 21² - 13² )
W = √ ( 441 - 169 )
W = √272
W = 16.49 inches
Therefore, the width of the TV will be equal to 16.49 inches.

An angle measures 46°. What is the measure of its complement?
(b) An angle measures 82°. What is the measure of its supplement?
Answer:
The complement of 46° = 44°
The supplement of 82° = 98°
Step-by-step explanation:
Complement means 90° - the angle (46°).
So, 90° - 46° = 44°
Supplement means 180° - the angle (82°)
So, 180° - 82° = 98°
The complement of 46° = 44°
The supplement of 82° = 98°
Complementary anglesComplementary angles are two angles that have a sum of 90°.
Supplementary anglesSupplementary angles are two angles that have a sum of 180°.
According to the question
a. An angle measures 46°.
The measure of its complement :
The meaning of complementary angle is two angles that add up to 90 degrees.
Complementary angles = sum of two angles = 90 degrees.
x° = y° + z°
90° = y° + z°
Given y° = 46°
z° = 90° - y°
z° = 90° - 46°
z° = 44°
The measure of its complement is 44°.
b. An angle measures 82°.
The meaning of supplementary angle is two angles that add up to 180 degrees.
Supplementary angles = sum of two angles = 180 degrees.
a° = b° + c°
180° = b° + c°
Given b° = 82°
c° = 180° - b°
z° = 180° - 82°
z° = 98°
The measure of its supplement is 98°.

Answer:
2, 0, -2, -4
Step-by-step explanation:
an = 4 − 2n
a1 = 4 - 2(1) = 2
a2 = 4 - 2(2) = 0
a3 = 4 - 2(3) = -2
a4 = 4 - 2(4) = -4
Answer:
(2, 0, -2, -4)
Step-by-step explanation:
a(1) = 4 - 2(1)
= 4 - 2
= 2
a(2) = 4 - 2(2)
= 4 - 4
= 0
a(3) = 4 - 2(3)
= 4 - 6
= -2
a(4) = 4 - 4(4)

Ike's igloo sold 501 ice cream cones today.They sold half as many chocolate ice cream cone as vanilla ones. How many of each were sold?
Answer:
Chocolate cones = x = 167 cones
Vanilla cones = y = 334 cones
Step-by-step explanation:
Let
The number of Chocolate cones = x
Vanilla cones = y
Ike's igloo sold 501 ice cream cones today.
x + y = 501.... Equation 1
They sold half as many chocolate ice cream cone as vanilla ones.
x = 1/2y
x = y/2
Cross multiply
y = 2x
We substitute 2x for y in Equation 1
x + 2x = 501
3x = 501
x = 501/3
x = 167
Solving for y
y = 2x
y = 2 × 167
y = 334
Therefore,
The number of
Chocolate cones = x = 167 cones
Vanilla cones = y = 334 cones

Answer:
- [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 5x - 2 ← is in slope- intercept form
with slope m = 5
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{5}[/tex]
