Please answer, I need help asap, thanks :p

Angle A = 15

Angle B: 105

Step-by-step explanation:

Angle A and 75° add up to 90°

75 + x = 90

x = 90 - 75

x = 15

Angle B and 75° add up to 180°

75 + x = 180

x = 180 - 75

x = 105

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
