Answer:

x = 25 degrees

Step-by-step explanation:

All the angles in a triangle must add up to 180 degrees.

That means: 2x + 15 + x + 10 + 3x + 5 = 180

Collect the like terms and put it on one side and put the whole numbers on the other.

2x + x + 3x = 180 - 15 - 10 - 5

6x = 150  

x = 25

Answer:

x=25

Step-by-step explanation:

add all the three equations and make it equal to 180 degrees because the sum of interior angles of a triangle is 180 degrees

2x+15+x+10+3x+5=180

6x+30=180

6x=180-30

6x=150

x=150÷6

x=25
