R u sure this is a college question.... well do 8 x 91 to get the numerator then 10 x 1 to get the denominator e.g ( x/y ) then simplify
Answer:
a=33 ( vertically opposite angles)
a+90=b( sum of opposite interior angle is equal exterior angle)
33+90 = b
b=123
15 percent of 359 is 53.85
subtract 359 minus 53.85 and you get 305.15
