Ineed this asap is it
a.30
b.45
c.75
d.90 i need this asap !

m<HAL = 5x

m<KAJ = 180-90-30 = 60

m<FA? = 60 (vertical angles)

3x+5x+60=180

8x=120

x=15

m<HAL = 5x = (5)15 = 75 degrees

its definatley   this on your answer choice?

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
