Question

Find the value of x to the nearest tenth. In a triangle, one angle is 46 degree and second angle is 20 degree. The adjacent side of 46 degree angel is 7 and opposite side is x.

Answer 1

Answer:

3.3

Step-by-step explanation:

We solve the above question using Sine rule

a/sin A = b/ sin B

x = a

A = 20°

b = 7

B = 46

Hence,

x/sin 20 = 7/sin 46

Cross Multiply

sin 20 × 7 = x × sin 46

Divide both sides by sin 46

x = sin 20 × 7/sin 46

x = 3.32825

Approximately x = 3.3
