7/12 and 1/3 don’t have the same denominator, so you can’t just add them right away. You have to give them the same bottom number. 1/3 = 4/12, so you can do it like this:

7/12 + 4/12 = 11/12

11/12 is in simplest form, so that should be correct! Hope this helps! :)

A field in the shape of a right triangle is bordered on one side by a stream, on another side by a road, and on a third side by

trasher [3.6K]

Answer:

42°

Step-by-step explanation:

For this problem, it may help you to draw it out to visualize it. You want to find the angle between the stream and road. Based on the description the triangle looks like this.

/ |

Stream(27) / | Road( 20)

/__|

Fence

You know the length of the road is 20, and the stream is 27. The angle can be found by using Cos∅=a/h. Adjacent to where the road and stream meet is the road, 20, and hypotenuse is the stream, 27.

So 20/27 = .74 = Cos∅

To find the angle ∅ use inverse cosine to get 42°.

Hope that helps and let me know if I did anything incorrectly!

Step-by-step explanation:

$\text{We know:}\\\\\sin(-\alpha)=-\sin\alpha\\\\\sin(\alpha\pm k\cdot360^o)=\sin\alpha\\\\===============================\\\\\sin(360^o-\theta)=\sin\bigg(-(\theta-360^o)\bigg)=-\sin(\theta-360^o)=-\sin\theta$
