Question

In ΔABC, c = 630 inches, ∠C=165° and ∠A=11°. Find the length of a, to the nearest inch.

Answer 1

Answer:

464

Step-by-step explanation:

Find other angle:

<B = 180 - 165 - 11 = 4

Then plug in (opposite sides go together):

$\frac{a}{sin 11}$ = $\frac{630}{sin 165}$

$a = \frac{630 sin 11}{sin 165} = 464.454 = 464$
