Question

Find the value of x in each triangle.

Answer 1

Answer:

x = 36

Step-by-step explanation:

1. It's important to know that the sum (in degrees) of all angles in a triangle is 180°.

• This means that 2x + 2x + x = 180.

2. (Solving)

Step 1: Simplify both sides of the equation.

• $(2x+2x+x)=180$
• $5x = 180$

Step 2: Divide both sides by 5.

• $\frac{5x}{5}=\frac{180}{5}$
• $x = 36$

Step 3: Check if solution is correct.

• $2(36)+2(36)+36=180$
• $72+72+36=180$
• $180=180$

Therefore, the answer is 36.
