A. The ratio of cups of sugar to butter is 3/4 : 1/8. Then multiply both ratios by 8.
8 x 3/4 = 6,
8 x 1/8 = 1.
3/4 : 1/8 is equal to 6 : 1. Therefore, 6 cups of sugar needed when there is 1 cup of butter.

Answer:
30
Step-by-step explanation:
all triangles =180
because 180 -120 =60whch is the missing inside angle
and we know that this is a right angle
so we subtact what we know to find what we dont
180-(60+90)=30
(150)
180-150=30
