Question

the triangle below is equilateral. find the value of y. 60° (2y + 4)° y = ?

Explanation:

Step1: Recall equilateral - triangle property

All angles in an equilateral triangle are 60°. So, we set up the equation \(2y + 4=60\).

Step2: Solve the equation for y

Subtract 4 from both sides: \(2y=60 - 4\), so \(2y = 56\). Then divide both sides by 2: \(y=\frac{56}{2}\).

Answer:

28
