The angle B of a triangle ABC is 26.87°.
Given that, ∠A=92°, b=6.93 cm and a=15.31 cm.
<h3>What is the sine rule formula?</h3>
In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
The sine rule formula=sin A/a = sin B/b =sin C/c.
Now, sin 92°/15.31 = sin B/6.93
⇒sin B/6.93=0.0652
⇒sin B=0.452
⇒B=26.87°
Therefore, angle B of a triangle ABC is 26.87°.
