HELP ASAP WILL GIVE BRAINLIEST

SOVA2 [1]

Answer:

1 7/10

Step-by-step explanation:

First, you would convert the first mixed number into an improper fraction. In this case, it would be 17/4.

The next step would be to multiply the two fractions. To re elaborate, we would be multiplying 17/4 * 2/5. If you don't know how to do that, ask me.

The product is 34/20. It says to simplify the answer into a mixed number, so that would be 1 14/20, simplified to 1 7/10.

Hope this helps! :)

URGENT!!

ss7ja [257]

Answer:

A. 14.7cm

Step-by-step explanation:

In Triangle ABC

$\angle A=60^\circ\\\angle B=45^\circ\\b=12cm$

We are to determine the measure of side a.

Using Law of Sines

$\dfrac{a}{\sin A}= \dfrac{b}{\sin B}\\\dfrac{a}{\sin 60^\circ}= \dfrac{12}{\sin 45^\circ}\\\\$Cross multiply\\a*sin 45^\circ=12*\sin 60^\circ\\$Divide both sides by sin 45^\circ\\\dfrac{a*sin 45^\circ}{sin 45^\circ}= \dfrac{12*\sin 60^\circ}{\sin 45^\circ}\\\\a=14.7$ cm (to the nearest tenth of a cm)$

The correct option is A.
