An equilateral triangles has an angle measure of x2. determine the value of x. round to the nearest tenth.

The answer is 30. An equilateral triangle is a triangle with all three sides equal. The angle measurements of a triangle always add up to 180 so the angle measurements are 60 for all three sides. 60 divided by 2 is 30 so that is your answer.

If an angle is x^2 then:

x^2+x^2+x^2=180 since there are 180 degrees in  a triangle

3x^2=180

x^2=180/3

x^2=60

sq root of x^2= sq root of 60

x=7.7
