Question

Find the value of y and x to the nearest tenth.

Answer 1

Well we can use sine to find 'x'.



Sine is \(\sf \dfrac{Opposite}{Hypotenuse}\)

\(\sf sin(53^ o) = \dfrac{x}{10}\)

Can you solve that? @LilRob

Answer 2

First find \(\sf sin(53^o)\)..

\(\sf sin(53^o) = 0.79863551\)

Plug that in:

\(\sf 0.79863551 = \dfrac{x}{10}\)

Multiply 10 to both sides, what's 10 * 0.79863551?

Answer 3

@LilRob

Answer 4

7.98 which rounds to 8. And that is the answer to both values? @iGreen.

Answer 5

No, you gotta multiply 10 * 0.79863551

Answer 6

Tell me what you get.

Answer 7

7.9863551 @iGreen.

Answer 8

Oh, sorry..xD

Yes, that's the value of 'x'. Rounded to the nearest tenth would be 8.

Answer 9

You're correct.

Answer 10

Now we have to find 'y'.

Answer 11

sorry I think both sides are supposed to be the same length, I just didn't in the picture I drew
