URGANT PLEASE HELP!!

Solve the triangle for x. (1 point)

A) 41.8°
B) 89.6°
C) 48.6°
D) 90.4°

Answer 1

it looks like c

Explanation:

its not quite 50 but its extreemly close so its got to be c

Answer 2

`12 {}^(2) = 9 {}^(2) + 8 {}^(2) - 2(9)(8)(cosx)`

`144 = 81 + 64 - 2(72)(cosx)`

`144 = 145 - 144(cosx)`

`- 144(cosx) = 144 - 145`

`(cosx) = ( - 1)/( - 144)`

`arccos( (1)/(144) ) = > a = 89.6`
