It should be 5/13 because the opposite angle from D is 12, which you would use if you are looking for sine. But, since you are looking for cosine, it is adjacent over hypotenuse. Therefore leaving you with 5/13, since your hypotenuse is always your longest side and the adjacent is the other side from the one opposite of the angle.
Answer:
1/3
Step-by-step explanation:
Hey There!
The slope of y=1/3x is 1/3
The number right in front of the x is the slope
Hope this helps :)
Hi! Let me help you!
Before I answer your question, I should first introduce you to triangles! There ae three triangles: Isosceles triangle, equilateral triangle, and scalene triangle. If I remember it right, isosceles triangles have at least one line of symmetry; an equilater triangle must have three lines of symmetry; a scalene triangle HAS NO line of symmetry.
Now, to answer your question: the answer is FALSE. Scalene triangles have no line of symmetry.
I hope this helped you!
Answer:

Step-by-step explanation:
Answer:
<em>180/7 deg and 1080/7 deg</em>
Step-by-step explanation:
The measures of two supplementary angles add to 180 degrees.
One angle measures x.
The supplement measures 6x.
The sum of the measures is 180 deg.
x + 6x = 180
7x = 180
x = 180/7
6x = 1080/7
