Answer 1

14. R= 60°

16. Equilateral and acute

Answer 2

Answer:

1. 60

2. 6

3. Equilateral

Step-by-step explanation:

1. A triangle's angles add up to 180 degrees. So, 60 + 60 = 120, and 180 - 120 = 60.

2. Knowing that all the angles are 60, we know that this is an equilateral triangle. Equilateral triangles are equal on all sides and angles, which helps us solve for the sides.

So, we do 3(7x) = 180

21x = 180

21/21x = 180/21

x = 6.

3. As said before, since the angles add up to 60, which means all the sides are equal. A triangle that has all equal signs is classified as an equilateral triangle.

It is also acute because all of the sides are less then 90!

Hope I helped!! :)
