Answer:

The missing side's length is 18.2

Step-by-step explanation: To find a missing side in a right triangle, you use the Pythagorean theorem to solve it. According to the Pythagorean Theorem, 12.6^{2} + 13.1^2 = x^{2}, so 158.76 + 171.61 = x^{2} ⇒ 330.37 = x^{2} ⇒ x ≈ 18.2.

suppose a triangle has two sides of length 32 and 35, and that the angle between these two sides is 120. what is the length of t
Vesnalui [34]
Using cosine rule, the length of the required side = sqrt(32^2 + 35^2 - 2 x 32 x 35cos 120)
= sqrt(1024 + 1225 - (-1120))
= sqrt(2249 + 1120)
= sqrt(3369)
= 58.04

57 is greater than x - 8
svlad2 [7]

This is an inequality.

This is what the statement should look like: 57 > x - 8

Now, you can actually "properly" reverse these meaning the equality sign changes too. So basically you can mirror them.

The "mirrored" inequality expression would look like this: x - 8 < 57

Now just like normal algebra, you can transpose these terms from 1 side to another and so, -8 would transpose to the right hand side and the operation would be the inverse or in this case, addition. The expression would look something like this: x < 57 + 8

Add them up and you get: x < 65 :D
