Question

Can someone answer for me please, if you're great at math.

The equation sin (35o) = 12/c can be used to find the length of AB. What is the length of AB? Round to the nearest tenth.

*A <35o ; CB = 12*

Answer 1

Assuming that c is the length of AB (as is usually the case in the angle-side notation for triangles):
If sin(35) = 12/c, we can transform by multiplying both sides by c, and dividing both by sin(35) to get
c = 12/sin(35)
