Question

Find cos B, sinB,tanb

Answer 1

Using right triangle relations, we will get:

• tan(B) = 1.05
• sin(B) = 0.735
• cos(B) =  0.7

How to find the value of the trigonometric equations?

We assume that bot triangles are equivalent, then the angle B will be the same as the angle Z.

Now remember the relations:

• tan(θ) = (opposite cathetus)/(adjacent cathetus).
• sin(θ) = (opposite cathetus)/(hypotenuse)
• cos(θ) = (adjacent cathetus)/(hypotenuse).

If we step on angle B, we have:

• opposite cathetus = 29.4
• adjacent cathetus = 28
• hypotenuse = 40.6

Replacing that, we get:

• tan(B) = 29.4/28 = 1.05
• sin(B) = 29.4/40.6 = 0.735
• cos(B) = 28/40.6 = 0.7
