Question

Helppp pleaseee asap

Answer 1

Attachment 1:- x = 17

sin D = EF/DF = 8/17

Attachment 2:- sin D = 8/17

cos D = ED/DF = 15/17

tan D = sin D / cos D = 8/15

sin F = DE/DF = 15/17

cos F = EF /DF = 8/17

tan F = sin F / cos F = 15/8

sin = opposite / hypotenuse

cos = adjacent / hypotenuse

tan = sin / cos (or) opposite / adjacent

Answer 2

x=17

sinD =
`(8)/(17)`

cos D would be 15 / 17

tan D would be 8/15

sin F is 15/17

cos F is 8/17

tan F is 15/8

Explanation:

To solve for x, use the pythagorean theorem -
`a^(2) + b^(2) = c^(2)`.

`8^2 + 15^2 = x^2\\289 = x^2\\17 = x`

For the Sin of D, you put the opposite side over the hypotenuse:

8 / 17

To find Cos, you do adjacent side over hypotenuse and for Tan you do opposite side over adjacent.

cos D would be 15 / 17

tan D would be 8/15

sin F is 15/17

cos F is 8/17

tan F is 15/8
