The equation tan(55 degree) equals startfraction 15 over b endfraction can be used to find the length of line segment a c. triangle a b c is shown. angle b c a is a right angle and angle b a c is 55 degrees. the length of a c is b and the length of hypotenuse b c is 15 centimeters. what is the length of line segment a c? round to the nearest tenth. 3.0 in. 9.8 in. 10.5 in. 12.8 in.

10.5 in

Step-by-step explanation:

The correct question is

The equation tan(55 degree) equals StartFraction 15 Over b EndFraction can be used to find the length of Line segment A C. Triangle A B C is shown. Angle B C A is a right angle and angle B A C is 55 degrees. The length of A C is b and the length of B C is 15 inches. What is the length of Line segment A C?

Note: BC is not the hypotenuse of the right triangle ABC

see the attached figure to better understand the problem  

In the right triangle ABC of the figure

we know that

----> by TOA (opposite side divided by the adjacent side)

solve for b

(x, y)→(x − 8, y − 7)
