Can someone please help me I’m taking the quiz now‼️

B. X=60 and y=11

Step-by-step explanation:

A supplementary angle or a line makes 180 degrees and 180 minus 125 is 55

55 divided by 5 is 11 so y =11

Amd x is 60 because 2 times 60 is 120 and 120+5 is 125

so it is choice B

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
