Question

Find value of x pleaseee

Answer 1

Explanation:

you can use the side angle side formula ( a form of Law of Cosines)

a^2 = b^2 + c^2 − 2bc cos(A)

where x = a , then

`x^(2)` =
`5^(2)` +
`3^(2)` - 2*5*3*cos(107)

`x^(2)` = 25 + 9 - 30 * (-0.292371)

`x^(2)` = 25 + 9 -8.7711511

x = 5.0228 cm
