Does anyone know how to do this if so pls help and explain the solution pls ! This is geometry btw

Consider lines AB and XY,

they intersect at the point P

Therefore,

AB and XY and interesting lines.

Intersecting lines give vertically opposite angles.

/ XPA and / YPB are vertically opposite angles

/ XPA~/ YPB as vertically opposite angles are equal.

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

∠cbe and ∠deb are same-side interior angles.
