Answer:
a = 30 degrees; b = 60 degrees; and c = 105 degrees.
Step-by-step explanation:
Angle a and the 30 degree angle are vertical angles and thus are equal.
Since the interior angles of a triangle always add up to 180 degrees, 30 + b + 90 degrees = 180 degrees, so that b must be 60 degrees.
Angle c and the 75 degree angle are straight angles, and so their sum must be 180 degrees. Thus, c = 105 degrees.
Given sets A = {t, u, v, w, x, y, z} and B = {p, q, r, s, t, u}. Find A and B

Answer:
okay so
so we have A and B = {t,u}
The answer is b (I think not really sure)

The correct answer is D. (3x - 4) (2x + 5)
Here's why:
6x2 + 15x - 8x - 20=
6x2 + 7x - 20
