Find x and the measure of each side of an equilateral triangle abc if ab = 6x - 8, bc = 7 + x, and ac = 13 - x. a. x = 6; all sides are 13 b. x = 10; all sides are 3 c. x = 3; all sides are 16 d. x = 3; all sides are 10

In the 30-60-90 triangle below side s has a length of and side r has a length

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.

Is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis.
