An exterior angle is the sum of the two other interior angles
<span>the three interior angles are 55 and 65 and 180-(55+65)=60 </span>
<span>so 60 + 55 = 115 </span>
<span>60 + 65 = 125 </span>
<span>65 + 55 = 120

brainlest answer.
First make it that both denominators are the same.

Then add both numerators

Your final answer should be
First, you factor and simplify (respectively) the numerator and denominator. Your equation becomes:

Notice, there is a (x + 7) on both the top and the bottom. Because of this, they cancel each other out. What is left is your answer:
Just use this formula
V= 1/2 bxhxl
