"the quotient of 60 and 10"?

What math expression means “the quotient of 60 and 10”?

Is δ pmr similar to δ smn ? if so, which postulate or theorem proves these two triangles are similar?

List the sides of δrst in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12

What happens to the area as the sliders are adjusted? what do you think the formula for the area of a triangle is divided by 2?
