Answer:
x = 20
y = 19
Step-by-step explanation:
(2x - 3)° + (3x - 7)° = 90° (complementary angles)
(2x - 3 + 3x - 7)° = 90°
(5x - 10)° = 90°
5x - 10 = 90
5x = 90 + 10
5x = 100
x = 100/5
x = 20
2y - 1 = 2x - 3 ( vertical angles)
2y = 2x - 3 + 1
2y = 2x - 2
2y = 2*20 - 2 (plug x = 20)
2y = 40 - 2
2y = 38
y = 38/2
y = 19
I think you need to multiply
Distribute
remember a(b+c)=ab+ac
we can actually divide both sides by x
5(4x+8)=4(6x-10)
distribute
20x+40=24x-40
minus 20x both sides
40=4x-40
add 40 both sides
80=4x
divide by 4
20=x

Answer:
Step-by-step explanation:
In quadrant II, the standard position angle is found by subtracting the reference angle from 180°.
180° -68° = 112°
__
In quadrant IV, the standard position angle is found by subtracting the reference angle from 360°.
360° -75° = 285°
__
In quadrant III, the standard position angle is found by adding 180° to the reference angle.
180° +22° = 202°
