Question

Find the value of x. Round your answer to the nearest tenth.​

Answer 1

13.9
it’s a special triangle and that side would be 8√3 which is 13.9

Answer 2

c. 13.9

Explanation:

we can work out the third angle

all angles add up to 180

90 + 30 = 120, 180 - 120 = 60

using law of sines

`(x)/( \sin(a) ) = (b)/( \sin(b) )`

where sin(a) = 60, b = 30 and sin(b) = 30

`(x)/(sin(60)) = (8)/( \sin(30) )`

`x = (8)/(sin(30)) * \sin(60)`

x = 13.9
