Question

Find the value for the given variables. Give the variables in simplest radical form. (as a square root)

Answer 1

Explanation:

for y

take 45 degree as reference angle

using cos rule

cos 45=adjacent/hypotenuse

1/
`√(2)`=10/y

y=10
`√(2)`

for x

take 45 degree as reference angle

using sin rule

sin 45=opposite/hypotenuse

1/
`√(2)`=x/10
`√(2)`

x
`√(2)`=10
`√(2)`

x=10
`√(2)`/
`√(2)`

x=10
