Answer:
x=15º
Step-by-step explanation:
180=25+8x+5+2x

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
