Answer:
x = 20
y = 26
Step-by-step explanation:
40 and 2x are vertical angles, so they're equal to each other.
40 = 2x
Divide both sides by 2
x = 20
We see that 40 and 5y + 10 are a linear pair, which means they add up to 180.
5y + 10 + 40 = 180
5y + 50 = 180
5y = 130
y = 26
Answer:
-8 + 7
Step-by-step explanation:
7 - 8 = -1
-8 + 7 = -1
Answer:
900 degrees
Step-by-step explanation:
Use the formula for interior angles
Sum = (n - 2) x 180
Sum = (7 - 2) x 180
Sum = 5 x 180
Sum = 900 degrees

Answer: 25
Step-by-step explanation:
Plug in x to the expression.
When there is the same base of exponents is being multiplied the exponents add together and the base stays the same.
So this simplifies to, 
.
This then solves to 25.
Answer:
x = 125°
Step-by-step explanation:
The sum of the angles around a point = 360° , then
90 + 145 + x = 360°
235° + x = 360° ( subtract 235° from both sides )
x = 125°
