Question

I don’t understand please help me out it’s geometry

Answer 1

x = -3

Step-by-step explanation:

Given m∠GHI = 154°, m∠THI = x + 25, and m∠GHT, we can write the following equation to find the value of x:

x + 135 + x + 25 = 154

• Add like terms.

2x + 160 = 154

• Subtract 160 from both sides.

2x = -6

• Divide both sides by 2.

x = -3
