Since AB is parallel to QR:

Angle A = Angel Q

Angle B = Angle R

(Corresponding angles)

Angle P is common to both triangles, PAB and PQR.

Therefore PAB and PQR are similar figures.

Similar figures have sides in the same ratio:

PA/PQ = PB/PR

Cross multiplying, we get:

PA × PR = PB × PQ

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
