Question

find the value of x.

Explanation:

Step1: Use the property of isosceles triangle

Since the two base angles are equal, the triangle is isosceles and \(7x + 5=19\).

Step2: Solve the equation for \(x\)

Subtract \(5\) from both sides: \(7x=19 - 5\), so \(7x = 14\).
Divide both sides by \(7\): \(x=\frac{14}{7}\).

Answer:

\(2\)
