PLEASE HELP SOON Find the value of x. Round to the nearest tenth. 27° х 34° 11 X = ? [?] 9 Law of Sines: sin A sin C sin B b a E

Tatiana [17]

The picture of the problem has been attached below :

Answer:

13.5

Step-by-step explanation:

Applying the sine rule to solve for x

SinA /a = SinB / b = SinC/ c

Sin 34 / x = Sin 27/11

Cross multiply :

11 * sin34 = x * sin 27

6.1511219 = 0.4539904x

Divide both sides by 0.4539904

6.1511219/0.4539904 = x

13.549 = x

x = 13.5
