Question

PLEASE CAN SOMEONE TELL ME IF IM SUPPOSE TO USE TAN OR SIN TO SOLVE 11b?

Answer 1

Answer:

Either or, it doesn’t make a difference here. If you used the tangent formula, you would need to use AC to find BC but if you used the sine formula you would need to use AB to find BC.

Answer 2

No, You use GCD take all measurements do GCD
