Answer:
sin F = a/c
Step-by-step explanation:
The sin ratio by definition for a given angle is the side opposite that angle over the hypotenuse. The only thing that will never change sides in a right triangle is the hypotenuse. In other words, no matter what angle you look at, while the side opposite one angle may be the adjacent side to a different angle, the hypotenuse is always the hypotenuse. That means that c is the hypotenuse in our triangle. The side opposite angle F is a, so the sin of F = a/c.
Line BD is perpendicular to line AC. both angles ADB and CDB are right angles.
4x+10=90
subtract 10 from both sides
4x=80
divide both sides by 4 to isolate x
x=20
plug in 20 for x in the equation (x+11) to find the measure of angle c
20+11=31°
the measure if angle c is 30°
