Answer:
y/12 = 3/17
y = 36/17
Step-by-step explanation:
solving and equation with one missing variable
step 1: multiply 12 on both sides of the equation
ex: y/12 = 3/17 (y = 36/17)
step 2: take your answer of y which is 36/17 and input it into y in your original equation then solve
ex: y/12 = 3/17 (36/17 /12 = 3/17)
3/17 = 3/17 (if both sides of the equation have the same number like 3/17 = 3/17 then that means your answer is true)

Using the quadratic formula
Answer:
Right angles is 90° so 90°+30°=120°.A straight line is 180°. So you do 180°-120° which is 60. So A=60°
