Δbcd is rotated 80° clockwise about the origin to form δklm. if m∠klm=30°, what is m∠bcd?

a.) m∠bcd = 30°
b.) m∠bcd = 50°
c.) m∠bcd = 80°
d.) m∠bcd = 110°

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
