An exterior angle is equal to the two opposite inside angles.
You are given the exterior angle and the two opposite inside angles so you can set up an equation to solve for x, then replace x in the equation to solve for the angle.
7x-16 = 4x + x+8
Simplify:
7x-16 = 5x+8
Add 16 to each side:
7x = 5x+24
Subtract 5x from each side:
2x = 24
Divide both sides by 2:
x = 24/2
x = 12
Now replace x with 12:
7(12)-16
Simplify:
84 -16
Subtract:
Answer is 68 degrees.

Hello!
To find the hypotenuse of a right triangle, we use the formula: a² + b² = c². In this formula, which is also known as the Pythagorean Theorem, a and b are the legs of the right triangle, and c is the hypotenuse, which is the value we are trying to find.
The value of leg a is 9 centimeters, and value of leg b is 12 centimeters. With those values, we can substitute it into our equation and solve.
(9)² + (12)² = c² (simplify the exponent)
81 + 144 = c² (simplify)
225 = c² (take the square root of both sides)
c = 15
Therefore, the length of the hypotenuse is 15 centimeters.
