Question

CAN SOMEONE PLEASE HELP ME WITH MY GEOMETRY HOMEWORK PLEASE?

Answer 1

Answer:

Option A

Step-by-step explanation:

The complete question is shown in the attachment.

The sum of angles in a triangle is 180 degrees.

This implies that:

$m\angle A+85+53=180$

m<A+138=180

m<A=180-138=42

Now we use the sine rule to find AC=b

$\frac{b}{\sin 85}=\frac{85}{\sin 42}$

This implies that:

$b=\frac{85}{\sin 42}*\sin 85$

$b=126.5$
