Suppose a triangle has two sides of length 32 and 35, and that the angle between these two sides is 120°. which equation should you solve to find the length of the third side of the triangle?

Which inequality is equivalent to -3x < -12? x < 4 , x < -4 , x > 4, x > -4

The measurement of one angle of a right triangle is 42° what is the measurement of the third angle? (there is no picture)
