Question

In △ABC, m∠A=45°, c=17, and m∠B=25°. Find a to the nearest tenth.

Answer 1

12.8

Explanation:

you have to use the law of sines to calculate it. the measure of angle c is 110 and you have to do

Sin(110)x=17sin(45)

and then it turns into 17sin(45)/sin(110)

then put it into desmos with it being in degrees mode
