I need help with one 1+16=14+2 is this true or false

Vlad1618 [11]

Answer:

That my friend is FALSE

Step-by-step explanation:

To figure something like this out you just need to add the numbers on both sides. If they end up to be the same thing then it is true. If not, its false.

1+16=14+2

17=14+2

17=16

Nope. 17 does not equal 16. So it is false.

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

My name is Ann [436]

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.
