Answer:
X=32
G=89°
Explanation:
sum of angles in a triangle is 180°
x+x-5+3x+25=180
X+X+3x=180+5-25
5x=160
divide both sides by 5
we will get
angle G= 3x+25
=3(32)+25
=96+25
= 121°
Sum of all the angles of a triangle = 180
x + 3x + 25 + x - 5 = 180
x + 3x + x + 25 - 5 = 180
5x + 20 = 180
5x = 180 - 20
5x = 160
x = 160/5
x = 32
∠G = 3x +25
= 3*32 +25
= 96 + 25
∠G = 121°
