Please Help Brainliest to whoever can give a clear explanation for this problem! In triangle ABC, , AC = 1, and AB = 5. Point D lies on ray AC such that . Compute AD.

See the attached sketch. Let denote angle ABC and denote angle CBD. Then .

From the sketch, we see that

Write in terms of . Recall the angle sum identity for tangent:

This gives us

and plugging in leaves us with

and so AD = 5 * 37/55 = 37/11.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.
