Angle PQR is a right angle. The three quadrilaterals shown are squares. The sum of the areas of the three squares is 338 square centimeters. What is the number of square centimeters in the area of the largest square?

169 cm²

Step-by-step explanation:

Recall that the area of the largest square is |PR|²

Also recall from Pythagoras Theorem that:

|PQ|² +|QR|² =|PR|² >1

Also we have that the sum of the areas of the three squares is 338 square centimeters.

This implies that:

|PQ|² +|QR|² +|PR|²=338>2

Put equation (1) into (2)

|PR|²+|PR|²=338

Simplify to get:

2|PR|²=338

Divide both sides by 2 to get:

|PR|²=338

|PR|²=169

plz yuo

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
