Answer:
x=13
Step-by-step explanation:
Divide both sides by -5 then solve the equation for x
The missing side and angles are 16.8 , 23.33 degree and 123.7 degree respectively.
<h3>What is a Triangle ?</h3>
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.

Answer:
i think 1004Step-by-step explanation:
Answer:
3 +4 i
Step-by-step explanation:
x + sqrt(yz)
Let x = 3 y=2 and z = -8
3 + sqrt(2*-8)
3+ sqrt(-16)
3 + sqrt(16) sqrt(-1)
We know sqrt(-1) = i
3 +4 i
