Question

SOMEONE HELP ME PLEASE

Answer 1

`(11)/(2)`

Explanation:

`(x)/(AB)`=cos60

x=
`(AB)/(2)`=
`(11)/(2)`

in a right angled triangle cosA=
`(adjacent)/(hypotenuse)`

so cosB=
`(x)/(11)`

`(1)/(2)`=
`(x)/(11)`

x=
`(11)/(2)`

Answer 2

• 5.5 units

Explanation:

x is the smallest side because it is opposite of 30° angle.

The side opposite to 30° is half the hypotenuse:

• BC = AB/2
• x = 11/2
• x = 5.5
