Question

the measure of a triangle is 3a+7b-8 if the measure of two sides is 6a+8b-7c and a-3b-2c find the measure of third side

Answer 1

Answer:

-4a+2b+9c-8

Step-by-step explanation:

(6a+8b-7c) + (a-3b-2c) + ( x ) = 3a+7b-8

7a+5b-9c + x = 3a+7b-8

x = (3a+7b-8) - (7a+5b-9c)

x = (-4a+2b+9c-8)
