Answer:
1/5 are females i think
Step-by-step explanation:
The angles are x =25, angle A = 20 and B = 70
<h3>How to solve for the angles?</h3>
The given parameters are:
A = x - 5
B = 2x + 20
Both angles are complementary angles.
This means that:
x - 5 + 2x + 20 = 90
Evaluate the like terms
3x = 75
Divide both sides by 3
x = 25
Substitute x = 25 in A = x - 5 and B = 2x + 20
A = 25 - 5 = 20
B = 2 * 25 + 20 = 70
Hence, the angles are x =25, angle A = 20 and B = 70

A is wrong since if the lower number was a low negative and you square it there is a small chance that it is grater then the square of the bigger number
B is wrong since... it's like when you multiply a negative. you have to flip the greater than less than sign
C is wrong since the bigger the denominator is the less of a number you get
