Question

PLEASE ANSWER ASAP!!!!!!!!

Answer 1

The missing side and angles are 16.8 , 23.33 degree and 123.7 degree respectively.

What is a Triangle ?

Triangle is a polygon with three sides , three angles and three vertices.

Given is triangle ABC , with sides  a = 8, c = 11, and m∠C=33 degree

The missing angle and side is given by Cosine rule of triangle

c² = a² + b² - 2ab cosC

11² = 8² + b²  - 2* 8 * b * cos 33

57 = b² -13.42 b

b²  -13.42b -57 = 0

b = 16.8

By sine rule

a / sin A = b/sin B = c/sinC

8 / sin A = 11 / sin 33

A = 23.33 degree

Similarly

B = 123.7 degree

Therefore the missing side and angles are 16.8 , 23.33 degree and 123.7 degree respectively.
