Question

Triangle ABC has the three angle side lengths of  2.1, 2.1 and 2.1. What is the angle measure of <A.

Is it ABC OR D
A- 2.1
B- 20
C-60
D- 180​

Answer 1

Answer: C) 60

Step-by-step explanation:

All equilateral triangles are also equiangular. This means all three angles are the same measure. If x was that measure, then

x+x+x = 180

3x = 180

x = 180/3

x = 60

Each angle is 60 degrees
