Question

Which equations could be used to solve for the unknown lengths of ABC? Check all that apply.

a) sin(45°) = BC
b) tan(45°) = AC
c) (AC) * sin(45°) = BC
d) cos(45°) = BC

Answer 1

The equations that could be used to solve for the unknown lengths of ABC are tan(45°) = AC and (AC) * sin(45°) = BC.

Step-by-step explanation:

The equations that could be used to solve for the unknown lengths of ABC are:

• b) tan(45°) = AC: This equation can be used to solve for the unknown length AC using the tangent function. To find AC, we can rearrange the equation as AC = tan(45°).
• c) (AC) * sin(45°) = BC: This equation can be used to solve for the unknown length BC using the sine function. To find BC, we can rearrange the equation as BC = (AC) * sin(45°).
