Answer:

x = 11

Step-by-step explanation:

(3x + 28) + (5x + 52) + ( 2x - 10) = 180

(3x + 5x + 2x) + (28 + 52 - 10) = 180

10x + 70 = 180

10x = 180 - 70

10x = 110

x = 11

Answer:

x= 11

Step-by-step explanation:

(3x + 5x) + (5x+52) + (2x-10)= 180 (sum of anglea in a triangle)

10x+80-10= 180

10x+70=180

10x=180-70

10x=110

x=110÷10

x=11
