Complementary angles: two angles that add to 90°
Supplementary angles: two angles that add to 180° (x)
angle "y" : y= 5x+6
180= (5x+6) + x
180=6x+ 6
174=6x
x=29
180- 29= 151
Answer: 151°
<em>√36 can be taken out of the root as 6. So it's a rational number.</em>
<em>About the perfect square, if we (√36)² then we get 36. and √36 is just 6.</em>
<em>For non-repeating decimal, √36 is already an integer.</em>

Answer:
a = 12 years
Step-by-step explanation:
Mark is 6 years older than his brother Sam. Now, we are asked to represent Sam’s age by a. This means that if Sam is a years old, Mark is (a + 6) years old.
The sum of their ages is 30, this means that when we add their ages together, we get the sum of thirty.
Mathematically this means a + a + 6 = 30
2a + 6 = 30
This is the equation needed to get a. To get a , we proceed to solve the equation to completion.
2a = 30 - 6
2a = 24
a = 24/2
a = 12
If you simplify it, you get 2x-10 or D
