The two angles are complementary because any angles across from each other are equal. From there you can figure out that the angles together form 180. After that all you need to do is subtract 60 from 180 to get 120.

how do I find the area of an equilateral triangle given the perimeter of 60 and the height of 17.3 cm?

guajiro [1.7K]

If perimeter is 60 so the side is 60 ÷ 3 = 20

Now we can apply the area formula for triangles;

$A=\frac{1}{2}.b.h\\
\\
A=\frac{1}{2}.20.17.3=10.17.3=173 \ cm^2$
