Answer:
5x
Step-by-step explanation:
. If the measures of angles A and B of triangle
ABC are each 2x + 5 and the measure of angle
C is 3x – 5, what is the measure of angle exterior
to angle A?
Using the theorem
The sum of interior angle of a triangle is equal to its exterior
Given the interior angles 2x+5 and 3x-5
Sum= 2x+5+3x-5
Sum = 2x+3x+5-5
Sum = 5x+0
Sum = 5x
Hence the measure of the exterior angle is 5x
