Answer:
6.3
Step-by-step explanation:
10.5 : 5 = x : 3
5x = 3 x 10.5 = 31.5
x = 6.3
220= 45*x. I hope you are satisfied with my answer.
Angle 10 is 140 degrees
Angle 2 = Angle 10 = 140 degrees (Vertically Opposite Angles)
Angle 5 + Angle 4 = Angle 2 (Corresponding Angles)
Angle 5 + Angle 4 = 140
90 + Angle 4 = 140 (Angle 5 is 90 degrees because c is perpendicular to d)
Angle 4 = 50
The answer is C.
If you multiply the top equation by 3 the x variable would become 2x * 3 = 6x
Multiplying the second equation by 2 the x variable becomes -3x * 2 = -6x
You would then have 6x - 6x, which would eliminate the x variable.
