Answer:
60°
Step-by-step explanation:
Total angle measurement for a triangle is 180°

This triangle is equilateral so it's angle is 60°.
Why is it equilateral? Because all sides of the triangle are equal (10 on all sides).

t = (A/sx) - r
Solve for t like this:
1) f=30
2) w=21
3) x=72
4) t=12
5) y=6
where are the expressions??
