let the exterior angle be x
x=60°+80°(being one exterior angle is equal to two interior angle)
x°=140°
Answer:
145
Step-by-step explanation:
angles in a pentagon add up to equal 540
Hence, 110 + 90 + 80 + 115 + v = 540
( note that we just created an equation that we can use to solve for v )
We now solve for v using the equation created
110 + 90 + 80 + 115 + v = 540
step 1 combine like terms
110 + 90 + 80 + 115 = 395
we now have 395 + v = 540
step 2 subtract 395 from each side
540 - 395 = 145
395 - 395 cancels out
we're left with v = 145

Answer:
C'
Step-by-step explanation:
Given
ABCD to A'B'C'D'
Required
Corresponding angle of C
ABCD to A'B'C'D' means that the following angles are corresponding
Hence, C' corresponds to C
