For positive acute angles A and B, it is known that sin A = 21/29 and cos B = 7/25. Find the value of sin(A + B) in simplest form.

Explain step-by-step how to simplify -5(2x – 3y + 6z – 10).

What is an alternate exterior angle

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39
