Answer 1

Q1. x = 17.1; y = 5.6

Q2. x = 9.7; y = 24.1

Explanation:

Use sine and cosine.

`sine=(opposite)/(hypotenuse)`

`cosine=(adjacent)/(hypotenuse)`

Q8.

We have:

`opposite=y\\\\adjacent=x\\\\hypotenuse=18\\\\\alpha=18^o\\\\\sin18^o\approx0.309\\\\\cos18^o\approx0.9511`

Substitute:

`(y)/(18)=0.309` multiply both sides by 18

`y=5.562\to y\approx5.6`

`(x)/(0.9511)=18` multiply both sides by 0.9511

`x=17.1198\to x\approx17.1`

Q9.

We have:

`opposite=y\\\\adjacent=x\\\\hypotenuse=26\\\\\alpha=68^o\\\\\sin68^o\approx0.9272\\\\\cos68^o\approx0.3746`

Substitute:

`(y)/(26)=0.9272` multiply both sides by 26

`y=24.1072\to y\approx24.1`

`(x)/(26)=0.3746` multiply both sides by 26

`x=9.7396\to x\approx9.7`
