Question

Triangle ABC has three sides that all measure 7 feet. What is the measure of Angle B?

Answer 1

an equilateral triangle (a triangle with equal sides) also has 3 equal angles

angle A= angle B = angle C

they sum to 180 degrees

180/3 = 60 degrees = angle B, A and C, 60 degrees each. or pi/3 radians

60+60+60 = 180
