Question

For the triangle above, find sin A. a. 36° c. 0.9323 b. 50° d. 0.385

Answer 1

the picture in the attached figure

we know that
in the right triangle ABC
sin A=opposite side angle A/hypotenuse

in this problem
opposite side angle A=BC-----> 10
hypotenuse=AB-----> 26
so
sin A=10/36------> sin A=0.3846------> sin A=0.385

the answer is
the option d. 0.385
