Tell whether the angles are complementary or supplementary. Then find the value of x.

this just confused me a bit. x - 20? They are complimentary so ik the other side has to be 20

Tell Whether The Angles Are Complementary Or Supplementary. Then Find The Value Of X.this Just Confused

Answers

Answer 1
As you should already know that the angle shown is 90°.

So,

x + (x - 20) = 90

Now we have to solve for x. To find x we need to isolate it (get it by itself)

Add 20 on both sides:

x + x = 110

Simplify:

2x = 110

Now divide 2 on both sides (to get x by itself)

x = 55


Let’s check our answer:

55 + ( 55 - 20) = 90

55 + 35 = 90

90 = 90

So your answer should be x = 55.

Answers

Answer: SU, TU, ST is the right answer

Step-by-step explanation: In a triangle

The largest side and the largest angle are opposite to each other

The shortest side and the shortest angle are opposite to each other.

So using the above axioms we can observe the triangle.

The largest angle is m∠U = 80° so the side opposite to it is the largest i.e. ST is the largest

The smallest angle is m∠T = 25° so the shortest side is SU

The third side will be the middle side as the angle ∠S is greater than 25° and less than 80°

So the sides in order from least to greatest are: SU, TU, ST

Find the value of x in the triangle shown below.

Answers

Answer:

102 degrees.

Step-by-step explanation:

Because the 3.3's are congruent (the same), this triangle is isosceles.

A property of isosceles means that the two angles are congruent.

39+39= 78

This means that the last angle must be 180-78.

The answer is almost certain to be 180

Find the lateral surface area of the cylinder. Round your answer to the nearest tenth.

i dont know lateral surface area lol

Answers

Answer:

72 pi

Step-by-step explanation:

Think of the lateral surface area as a label on a soup can. When you roll it out, then the circumference becomes the length and the height of the cylinder becomes the width or vise versa. So if 2(pi)(r) is the formula for the circumference, then that is 8. 8*9 is 72 and you multiply that by pi to get 72 pi
