Question

the triangle below is isosceles. find the value of z. 8z + 8 72 z = ?

Explanation:

Step1: Set the two equal sides equal

In an isosceles triangle, the two marked sides are equal. So we set \(8z + 8 = 72\).

Step2: Solve for z

Subtract 8 from both sides: \(8z = 72 - 8 = 64\). Then divide both sides by 8: \(z=\frac{64}{8}=8\).

Answer:

8
