Sum of angles in a triangle = 180°, then:
∠H + ∠F + ∠G = 180°
(x°) + (x-5)° + (3x+25)° = 180°
Remove all parenthesis and computr
x+x-5+3x+25 = 180
5x + 20 = 180
5x=160
x = 32°, then ∠G = 3x+25 = 3(32)+25 = 121°

Answer:
x = 4
Step-by-step explanation:
expand out the brackets to get 7 - 2x = 2x - 8 - 1
we can then add 2x to both sides to get 7 = 4x - 8 - 1
add 9 to both sides to get 16 = 4x
divide both sides by 4 to get x = 4
hope that helps
