Question

NO LINKS!!! Find the measurement indicated. Round your answer to the nearest tenth.​

Answer 1

Answer:

Solutions given;

Using cosine rule

b²=a²+c²-2*a*c*cos B°

b²=15²+8²-2*15*8*cos39

b²=102.48

b=$\sqrt{102.48}$

b=10.12

b=10.1

Using sine rule

$\frac{sin A}{BC} = \frac{sin B}{AC} =\frac{sin C}{AB}$

$\frac{sin 29°}{15} =\frac{sin C}{8}$

Doing criss cross multiplication

Sin C=$\frac{sin 29°}{15} ×8$

m<C=Sin -¹(0.29)

m<C=14.98

m<C=15°is a required answer.
