Question

Find the missing sides of the triangle

Answer 1

F=24 and e=12
`√(3)`

Explanation:

Answer 2

D

Explanation:

Using the sine ratio in the right triangle and the exact value

sin30° =
`(1)/(2)` , then

sin30° =
`(opposite)/(hypotenuse)` =
`(12)/(f)` =
`(1)/(2)` ( cross- multiply )

f = 24

----------------------------------------------------------------

Using the cosine ratio and the exact value

cos30° =
`(√(3) )/(2)` , then

cos30° =
`(adjacent)/(hypotenuse)` =
`(e)/(f)` =
`(e)/(24)` =
`(√(3) )/(2)` ( cross- multiply )

2e = 24
`√(3)` ( divide both sides by 2 )

e = 12
`√(3)`
