Q: Quadrilateral P'Q'R'S' is similar to quadrilateral PQRS, where P'Q'R'S similar to quadrilateral PQRS, where P,Q,R and S correspond to P' Q' R' S ,respectively. The Measure of angle P is 30° , the measure of angle Q is 50° , and the measure of angle R is 70°. The angle of each side of P' Q' R' S' is 3 times the length of each corresponding side of PQRS. What is the measure of angle P'?

"x = 8a(b+9): Solve for a in 3 Steps"

x = 8a(b+9)

Solve for a in terms of b and x. Sounds simple, but 3 of the 4 answer choices are built from common algebra slip-ups 🧩

Since b is positive, b+9 ≠ 0, so we can safely divide both sides by 8(b+9):
