Pls help:Find all the missing elements:

Step-by-step explanation:

In order to find B we must first angle C

To find angle C we use the sine rule

That's

From the question

a = 15

A = 70°

c = 14

So we have

C = 61.288

Since we've found C we can use it to find B.

Angles in a triangle add up to 180°

To find B add A and C and subtract it from 180°

That's

A + B + C = 180

B = 180 - A - C

B = 180 - 70 - 61.3

To find b we can use the sine rule

That's

b = 11.9921
