tax gets added to the price of the camera
so the equation is:
x + 0.07x = 45; x = $42.06
Given:
Triangle LJK.
LJ = 89 in, LK = 28 in and m∠L = 42°
To find:
The length of missing side JK.
Solution:
LJ = k = 89
LK = j = 28
JK = l = ?
Using law of cosine:

Substitute the given values.





Taking square root on both sides.

The length of the missing side is 70.7 in.
Answer:
2.5, 6 and 6.5 inches.
Step-by-step explanation:
5 + 12 + 13 = 30
So the shortest side = 5/30 * 15 = 1/6 * 15
= 2.5 inches.
The longest = 13 / 30 * 15 = 13/2
= 6.5 inches,
and the third = 12/30 * 15
= 6 inches.
