Answer:

Hey there!

What we know:

  • The three triangles (two smaller ones and one larger one, are all right triangles)
  • Measure of angle A is 42 degrees.
  • Measure of angle C is 58 degrees.
  • AC is 65 m.

What we would like to know:

  • AB
  • BD

First, let's find AB.

Sine 58= AB/65

Solving for AB, we see that it is about 55.12 m.

Next, let's find BD.

Sine 42= BD/55.12

Solving for BD, we see that it is about 36.88 m.

Let me know if this helps :)
