Question

question 3 (1 point)
find the value of x.
(4x + 8)°
x =

Explanation:

Step1: Recognize the triangle type

The triangle with all sides equal (marked with tick - marks) is an equilateral triangle. In an equilateral triangle, each angle is \(60^{\circ}\).

Step2: Set up the equation

We have the equation \(4x + 8=60\).

Step3: Solve the equation for \(x\)

Subtract \(8\) from both sides: \(4x=60 - 8\), so \(4x = 52\).
Divide both sides by \(4\): \(x=\frac{52}{4}\).

Answer:

\(x = 13\)
