A30°-60°-right triangle is half of what other kind of triangle? select one of the options below as your answer. a. equilibrium triangle b. obtuse triangle c. equilateral triangle d. all of the above

Option C - equilateral triangle is the right answer.

Step-by-step explanation:

A 30°-60°-90° is half of what other kind of triangle?

The answer is equilateral triangle.

An equilateral triangle can be split into two triangles measuring 30°-60°-90° triangles, by the altitude from any vertex.

The 30°-60°-90° triangle is a right triangle, where the other two acute angles are 30 and 60 degrees.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
