Select all of the equations that represent a correct ratio between the angles and sides in abc as indicated above.

h = 11/sin 40°

h = 11/cos 50°

Step-by-step explanation:

Angle A = 40°

Angle C = 50°

For sin, do opposite leg divided by the hypotenuse. (sin 50° = 0.6428)

0.6428 = 11/h

0.6428h = 11

Divide each side by 0.6428.

h = 17.1

For cos, do adjacent leg divided by the hypotenuse. (cos 40° = 0.6428)

0.6428 = 11/h

0.6428h = 11

Divide each side by 0.6428.

h = 17.1

The reason the other answer choices are wrong is because they don't use the right formulas for sin and cos. The formula for sin is opposite leg/hypotenuse. The formula for cos is adjacent leg/hypotenuse. But the other wrong answer choices used the sin formula for cos, and the cos formula for sin.

(By the way, I got this right on my assignment.)

Hope this helps!

the correct answer is 5 6 and 7
