You need to use the law of cosine:
B^2 = A^2 + C^2 - 2ACcos(b)
55^2 = 90^2 + 50^2 - 2(50)(90)cos(b)
0.841666 = cos(b)
b = 32.68
Respuesta:

Explicación paso a paso:
Dado :
-2- | -2 | - | -3 | +3
Los números entre barras verticales son valores absolutos y se tratan como positivos:
-2 - +2 - +3 + 3 = - 2-2-3 + 3 = - 4
| -1 | + | -1 | - | -3 |
Los números entre barras verticales son valores absolutos y se tratan como positivos
1 + 1 - + 3 = 1 + 1-3 = - 1
Answer:
MV = 160 (and %50 sure) X = 27
Step-by-step explanation:
To find MV we just have to subtract the two lengths of the perimeter that we do know, minus the total perimeter, and find the difference. (using that its, 605-160-285 = 160) with that knowledge, we can say two things. MV = 160, and <V = <T by the two side lengths being congruent. With that, we can say that X + X +X+99 = 180, and then just find X, 27+27+27+99=180.
