Answer:(5,12)
Step-by-step explanation: 2.5 x 2= 5
6 x 2= 12
X = -23 - 47
x = -70
-70 + 47 = -23
The answer is A because there are only acute angles
Answer:
17°
Step-by-step explanation:
Let x represent the measure of the angle.
(90 -x) = 5 + 4x . . . . the complement is 5° more than 4 times the angle
85 = 5x . . . . . . . . . . add x-5 to both sides
17 = x . . . . . . . . . . . . divide by 5
The measure of the angle is 17°.
