Question

Does anyone know the answer plz ?

Answer 1

a=20,
`b=10√(3)`

Explanation:

SOH-CAH-TOA

Tan = O/A

Tan(60)= b/10

`b=10√(3)`

Cos = A/H

cos(60) = 10/a

a=20

Answer 2

a = 20; b = 10sqrt(3)

Explanation:

The ratio of the lengths of the sides of a 30-60-90 triangle is

1 : sqrt(3) : 2

b = 10 * sqrt(3)

b = 10sqrt(3)

a = 2(10)

a = 20

Answer: a = 20; b = 10sqrt(3)
