Question

Anyone want to answer the number for X???????

Answer 1

`(√(10) )/(2)`

Explanation:

Using cosine (since that is adjacent over hypotenuse), cos(60)=1/2 so your answer is hypotenuse*1/2=
`√(10)*(1)/(2)=(√(10) )/(2)`

Answer 2

`x = (√(10) )/(2)`

Explanation:

Using Pythagoras Theorem:

The triangle has hypotenuse of √10 , opposite side x, angle 30°

Using the formula:

`sin(A) = (opposite)/(hypotenuse)`

`sin(30)= (x)/(√(10) )`

`x = sin(30) * √(10)`

`x = (√(10) )/(2)`
