Question

What is the value of sin A?

Answer 1

Sine is opposite over hypotenuse so we'd have 7 over the square root of 130. The square root of 130 is 11.4017 approximately so you should have 7 over 11.4017 (you can leave out the one and the seven) Does this help you?

Answer 2

0,61

Explanation:

According trigonometry, we have the next relations

`Sen \theta = (side-opossite)/(hypotenuse)`

In our case and according the picture, we have

`Sen A = (side-opossite)/(hypotenuse) = (7)/(√(130))`

`Sen A = 0,61`
