Question

In ΔABC, if the lengths of sides a and c are 8 centimeters and 16 centimeters, respectively, and the measure of is 35°, what is the measure of to two decimal places?

16.67°



17.50°



26.57°



35.53°

Answer 1

16.67°

Explanation:

Answer 2

sin(A)/a= sin(C)/c, therefore sin(A) would = asin(C)/c= sin(35deg)/2. So, A then = arc sin(sin(35deg)/2)= 16.67
