Question

Use special right triangles to solve for y. the sides are x, y, 7 and 45 and 90 are the two angles i have.

Answer 1

X=7. Y=7 sq rt of 2 =9.9

Answer 2

Explanation:

From the given figure and the information, using trigonometry,

`(x)/(7)=tan45^{{\circ}}`

⇒
`(x)/(7)=1`

⇒
`x=7`

Also,
`(x)/(y)=sin45^{{\circ}}`

⇒
`(7)/(y)=(1)/(√(2))`

⇒
`y=7√(2)`

⇒
`y=9.9`

Thus, the values of x and y are 7 and 9.9 respectively.
