Question

Triangle ABC is a right triangle and cos(22.6o)=. Solve for b and round to the nearest whole number. Which equation correctly uses the value of b to solve for a? tan(22.6o) = tan(22.6o) = tan(22.6o) = tan(22.6o) =

Answer 1

HELLO DEAR,


The cosine of an angle is equal to the adjacent side divided by the hypotenuse.

In a right triangle, the hypotenuse is the longest side.

Its value is 13.

It also follows that B is the adjacent side.

To solve for B,

B = 13 cos 22.6˚ = 12

The tangent of the angle is equal to the opposite side divided by the adjacent side.
Since B is known, therefore the answer is

tan(22.6˚) = a/12 


I HOPE ITS HELP YOU DEAR,. THANKS
