Answer:
m∠A = 48.81°
Step-by-step explanation:
Given triangle is a right triangle and we have to measure ∠A.
Since, opposite side and adjacent sides of angle A has been given
So we will apply tangent rule to get the measure of angle A.
tan(∠A) =
tan(∠A) = 
∠A = 
∠A = 48.814
≈ 48.81°
When X = -9 Y = 1 you can find this by going to -9 on the x axis and finding where the line is there
56 + 32 = (8 x 7) + (8 x 4) = 8(7 + 4) (Answer C)
A and c are true ! I hope this helps
