Answer:
By substituting x and y vars with that in (x, y)
Step-by-step explanation:
2 * (-3) + 3 * 4 = 6 solution

So angles in a triangle add up to 180
Angle B is 50 and angle E is 90
90+50=140
180-140=40°(angle A)
Now the other triangle
Angle C is 62 and angle E is 90
90+62=152
180-152=28
40-28=12
hope this helped but I can't help with the second one
Well you shaded in two of the six, so it is 2/6.
