Answer:
Correct answer is x = 28°
Step-by-step explanation:
Okay we know Angle A is 2x + 2
Angle B is 90
Angle C is 180 - 148 = 32 ( straight line angle is 180)
Sum of all angles should be 180 in a triangle
which means
A + B + C = 180
2x + 2 + 32 +90 = 180
2x + 124 = 180
2x = 180-124
2x = 56
x = 56/2
x = 28
Answer:
It's dividing by 3 everytime, so 1/3
Step-by-step explanation:
X*y=72
x = 5y-2
x=72/y
72/y=5y-2
72=5y^2-2y
5y^2 -2y - 72 = 0
(5y+18)(y-4)=0
y = -18/5 discard
or y = 4
4x=72
x=18
(18,4)
