Triangle X Y Z is shown. The length of X Z is 12, the length of Y Z is 11, and the length of Y X is 6.
LenaWriter [7]

Answer:

84 degrees

Step-by-step explanation:

Applying the Cosine Rule (Choice 2 is the correct one)  :-

12^2 = 11^2 + 6^2 - 2*11*6 cos Y

144 = 121 + 36 - 132 cos Y

cos Y = (121 + 36 - 144) / 132

cos Y = 0.09848

Y = 84.3 degrees

nalin [4]
Hey there! 

These are the steps involved in answering the question:

Change 8% into a decimal. To do this, just move the decimal place, 2 places to the left.
You get 0.8

Now, multiply 0.8 by 44. 
0.8 x 44 = 35.2

So, the final answer is: 35.2.
