Answer:

x=22

Step-by-step explanation:

4x+2+x+3x+2=180

collect like terms

4x+x+3x=180-(2+2)

8x=180-4

8x=176

make x the subject of the formula

x=176/8

x=22

Answer:

4x + 2 + x + 3x + 2 = 180 (all angles of a triangle will equal 180 degrees)

Combine like terms:

8x + 4 = 180

-4            -4

8x = 176

Divide by 8 on both sides:

X = 22

So now we find the angles.

4 x 22 + 2 = 90 degrees for 4x + 2

3 x 22 + 2 = 68 degrees for 3x + 2

22 degrees is for X
