Find the missing parts of the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropriate. a = 8.6 in.
b = 13.9 in.
C = 16.5 in.

A. A = 31.40, B = 57.40, C = 91.2°

B. A = 33.49, B = 55.4", C = 91.2°

C. No triangle satisfies the given conditions.

D. A = 29.4°, B = 57.4º, C = 93.2°

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is 62.8 cubic units
