Let y be the length of the third side. By the Pythagorean theorem,
y² + x² = 3² = 9
so that
y = √(9 - x²)
(taking the positive root because one expects length to be positive)
Then by the definitions of sine, cosine, and tangent, we have
sin(θ) = x / 3 → θ = sin⁻¹(x / 3)
cos(θ) = √(9 - x²) / 3 → θ = cos⁻¹(√(9 - x²) / 3)
tan(θ) = x / √(9 - x²) → θ = tan⁻¹(x / √(9 - x²))

You win an online auction for a toy. Your winning bid of $35 is 70% of your maximum bid. How much more were you willing to pay for the toy than you actually paid?
Answers
If you divide 35 by 7, you will find what 10% of your maximum bid is.
35/7 = 5
5 = 10%
Multiply your value of 10% by 10 to get 100%.
5*10 = 50
Your maximum bid would be $50. You actually spend $35. To find the amount more you were willing to pay, subtract the two values.
$50-$35 = $15
Answer: You were willing to pay 15 more dollars than you did.
Based on the amount that you bid and its percentage out of what you would pay, the amount that you were willing to pay more was $15
The winning bid of $35 is only 70% of what you would have paid at most.
Your maximum bid would therefore have been:
= 35 / 70%
= $50
The amount that you were then willing to pay more than your bid was:
= Maximum bid - Winning bid
= 50 - 35
= $15
In conclusion, you were willing to pay $15 more.

What is the image of (2,3)(2,3) after a reflection over the line y=-xy=−x?
Answers
Answer:
After the reflection over the line y = -x, the image of the point is: (-3,-2)
Step-by-step explanation:
When a given point is reflected over a line the point only changes place but the distance between the point and the line remains same.
Let (x,y) be a point on the plane
and
y = -x be a line on the plane
When a point is reflected over a line y = -x , the coordinates of the point are exchanged which means x becomes y and y becomes x and both are negated
So (x,y) will become (-y,-x)
Given point is:
(2,3)
After the reflection over the line y = -x, the image of the point is: (-3,-2)

The opposite is true for when the leading coefficient is positive. When the degree is odd one end will point downwards while the other points upwards. When the degree is even, both ends point in the same direction.

Step-by-step explanation:
Put all the like terms together
(4a^2 - a^2) - (7b + b) + 2ab
then simplify
(4a^2 - a^2) = 3a^2
(-7b + b) = -6b
then rewrite
3a^2 - 6b + 2ab
Answer:
3a^2 - 6b + 2ab
Step-by-step explanation:
Add like terms together so shifting the equation a little to make it easier to add:
4a^2 - 7b + 2ab - a^2 + b
4a^2 - a^2 - 7b + b + 2ab
3a^2 - 6b + 2ab
A single die is rolled twice. Find the probability of rolling an
Odd number the first time and a number greater than 4 the second time.
Answers
Answer: 1/6
Step-by-step explanation:
A die has 6 numbers which are 1, 2, 3, 4, 5 and 6.
Odd numbers in a die = 1, 3 and 6
Numbers greater than 4 = 5 and 6
Probability of rolling an odd number = 3/6 = 1/2
Probability of rolling a number greater than 4 = 2/6 = 1/3
We then multiply both values gotten. This will be:
= 1/2 × 1/3
= 1/6
Therefore, the probability of rolling an odd number the first time and a number greater than 4 the second time is 1/6.
The probability of rolling an odd number the first time and a number greater than 4 the second time is 1/6
The sample space of a single die is
[tex]\mathbf{S = \{1,2,3,4,5,6\}}[/tex]
So, the total sample is 6
The odd numbers are
[tex]\mathbf{Odd = \{1,3,5\}}[/tex] --- 3 odd numbers.
So, the probability of selecting an odd number is:
[tex]\mathbf{P(Odd) = \frac 36}[/tex]
Simplify
[tex]\mathbf{P(Odd) = \frac 12}[/tex]
The numbers greater than 4 are
[tex]\mathbf{Greater = \{5,6\}}[/tex] --- 2 numbers greater than 4.
So, the probability of selecting a number greater than 4 is:
[tex]\mathbf{P(Greater) = \frac 26}[/tex]
Simplify
[tex]\mathbf{P(Greater) = \frac 13}[/tex]
The probability of rolling an odd number the first time and a number greater than 4 the second time is calculated as follows:
[tex]\mathbf{P = P(Odd) \times P(Greater)}[/tex]
So, we have:
[tex]\mathbf{P = \frac 12 \times \frac 13}[/tex]
[tex]\mathbf{P = \frac 16}[/tex]
Hence, the probability is 1/6

Both triangles are congruent, Hence Angles of both triangle will be equal,
We have got two angles,
LP = 59°, LT = 75°
let the third angle be x
The sum of all angles of a triangle is 180°
So,
59° + 75° + x = 180
x = 46°
a) ST = 8m
b) SU = 7m
c) mLR = 75°
d) mLQ = 46°
