1. what is the sum of the interior angles of a triangle?

a. 180 degrees b. 90 degrees c. 360 degrees d. 45 degrees

1. what is x? 5x + 5 = 20

a. x = 20 b. x = 5 c. x = 3 d. x = 4
how many sides does a triangle have?
5 sides b. 3 sides c. 2 sides d. 0 sides

Explanation:

Step1: Solve the equation \(5x + 5=20\)

Subtract 5 from both sides: \(5x=20 - 5\), so \(5x = 15\).

Step2: Find the value of \(x\)

Divide both sides by 5: \(x=\frac{15}{5}=3\).

Answer:

1. A. 180 Degrees
2. C. \(x = 3\)
3. B. 3 Sides
