Question

Given: b = 600, B = 11°, C = 75° in triangle ABC; find a. (Round the answer to the nearest whole number.) a =

Answer 1

Use the Law of Sines:

600 a
---------- = ---------- where 94 came from subtracting (11 + 75) from 180.
sin 11 sin 94

Solve this for side a.

Answer 2

a = 3136.85

Explanation:

We have law of sines
`(a)/(sinA)=(b)/(sinB)=(c)/(sinC)`

Here given b = 600, B = 11°, C = 75°

We also have A

A+B+C = A + 11 +75 = 180

A = 180 - 86 = 94°

`(a)/(sin94)=(600)/(sin11)\\\\a=3136.85`
