Answer:
143°
Step-by-step explanation:
The sum of angles in a triangle should be 180, so ∠1 = 180-53-90 = 37.
∠1 and ∠3 should add up to 180, so ∠3 must be 180-37 = 143.
You cross multiply. 20x4=5x
5x=80
x=16
The problem is already in standard form but to get it into slope intercept form you rewrite the equation so it looks like
6y=-5x+7 divide all by 6
y=-5/6x+7/6
slope being -5/6 and b being 7/6
