Question

Given right triangle ABC . To the nearest degree, find the measure of angle B. 20° 43° 47° 70°

Answer 1

The answer is "70°"

Explanation:

In the given question an attachment file is missing. so, the attachment file and its solution can be defined as follows:

Given:

ABC is the right triangle.

Find B=?

Solution:

`\Rightarrow \sin \theta= (p)/(h)\\\\`

`\Rightarrow \sin B^(\circ)=(AB)/(AC)= (4.8)/(5.1)\\\\`

`\Rightarrow \sin B^(\circ)= .941`

`\Rightarrow B^(\circ)= \sin^(-1) (0.941)\\\\\bold{\sin^(-1) (0.941) = 70.2^(\circ)}\\\\\therefore \ \ \ \ \bold{B^(\circ) = 70^(\circ)}`
