Given:
In triangle XYZ, x = 27 cm, y = 79 cm and
.
To find:
The length of z.
Solution:
In triangle XYZ, using the Law of cosine, we get

Putting the given values in the above formula, we get




Taking square root on both sides.


Approx the above value to the nearest number and side length cannot be negative. So,

Therefore, the length of z is about 102 cm.
Is that a minus sign in between the x) and x=8?
The perimeter is everything added up, since its not a square then you add not multiply. 24+24=48 and 16+16=32, add 32 and 48 and get 80. Answer:80
