Short Answer C
Nice little problem. The catch is that alpha and beta both add up to 90 degrees. 
Here's why.

α + β + right angle = 180° All triangles have 180° A right and = 90°.
α + β + 90 = 180  Right angles are 90° Now subtract 90° from both sides
α + β = 180 - 90
α + β = 90

Now all you have to do is put in the x values for alpha and beta and equate them to 90

5x/3 + 20 + 2x/3 + 14 = 90  Collect the light terms.
5x/3 + 2x/3 + 20 + 14 = 90
7x/3 + 34 = 90                     Subtract 24 from both sides.
7x/3 = 90 - 34                           
7x/3 = 56                             Multiply by sides by 3
7x = 3*56
7x = 168                              Divide by 7
x = 168/7
x = 24

That's not quite the answer
The question wants alpha.
α = 5x / 3 + 20
α = 5*24/3 + 20
α = 120/3 + 20
α = 40 + 20
α = 60

In the first quadrant you start at (7,3) and move 5 unit left
AveGali [126]

Answer:

That would be (2,3)

Step-by-step explanation:

When we're moving left in the coordinate plane, we are subtracting the x-coordinate by how much distance we move.

In this case, 7-5=2, so the new x-coordinate is 2, but the y-coordinate doesn't change since we're going horizontally and not vertically.
