Question

find the value of x in the triangle shown below.
x = □°

Explanation:

Step1: Identify triangle type

Two sides = 5, so isosceles triangle.

Step2: Determine angles

Equal sides → equal opposite angles (x). Included angle = 70°.

Step3: Sum of angles in triangle

Sum = 180°, so 70° + 2x = 180°.

Step4: Solve for x

2x = 110° → x = 55°.

Answer:

55
