Question

Hw 43 special right triangles

Answer 1

Explanation:

Use the fact that sin 30 =0.5 and cos 30 = sqrt 3/2

we have answers as

8. u=16 and v =
`8√(3)`

9) y=5 and x=
`5√(3)`

10) tan 30 =
`(1)/(√(3) )`

So y=
`4√(3)`

x=
`8√(3)`

11) a=22 and b=11

12) b=1.5 and a=
`1.5√(3)`

13) y=
`20√(3)`

and x=10
