Answer:

x=15º

Step-by-step explanation:

180=25+8x+5+2x

180=30+10x

180-30=10x

150=10x

15=x

Answer:

x = 15

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180 , that is

2x + 5 + 25 + 8x = 180 , simplify

10x + 30 = 180 ( subtract 30 from both sides )

10x = 150 ( divide both sides by 10 )

x = 15
