Question

HELP!!! use the law of sines! ​

Answer 1

Answer:

21.28

Step-by-step explanation:

Hey There!

So the law of sines says

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

To solve for c we just plug in the values that are given to us

$\frac{25}{sin38} =\frac{c}{sin31.6}$

step 1 multiply each side by sin31.6

now we have

$c=\frac{25sin31.6}{sin38} \\c=21.2773548$

assuming that you have to round

if you're supposed to round to the nearest whole number then the answer is 21

if you're supposed to round to the nearest tenth then the answer is 21.3

if you're supposed to round to the nearest hundredth then the answer is 21.28
