Answer:

the answer is 50 degrees

Step-by-step explanation:

the sum of all three angles of a triangle is always 180 degrees.

first you have to combine all terms, equal it to 180, and then solve for x.

4x-20+2x+2x=180

8x-20=180

8x=200

x=25

then to find angle G you multiple x times 2 (2x)

2 × 25 = 50
