Answer:
The measure of m∠B = 60°
Step-by-step explanation:
The given parameters are;
The length of the sides of ΔABC includes;
Side AC = 7.12 cm
Side BC = 7.12 cm
Side AB = 7.12 cm
Therefore, given that all the sides of the triangle are equal, we have that the triangle is an equilateral triangle
The measure of the each interior angle of an equilateral triangle = 60°, by definition of equilateral triangle
∴ The measure of m∠B = 60°.
