Question

directions: find the value of each variable. 5. 4x + 23 10x - 1 78° 78°

Explanation:

Step1: Use the property of isosceles triangle

In an isosceles triangle, sides opposite equal angles are equal. So, \(4x + 23=10x - 1\)

Step2: Solve the equation for \(x\)

Subtract \(4x\) from both sides: \(23 = 6x-1\)
Add \(1\) to both sides: \(24=6x\)
Divide both sides by \(6\): \(x = 4\)

Answer:

\(x = 4\)
