B and D
Step-by-step explanation:
vertical angles are ones that are formed by intersecting lines, and they are also equal to each other and opposite of each other.
its not A because they are not equal to each other.
B is correct because they are formed by intersecting line and equal to each other
C is incorrect since theres some random line that doesnt completely pass through on either side
D is correct
For this case we have that by definition of trigonometric relations of rectangular triangles, that the cosine of an angle is given by the leg adjacent to the angle on the hypotenuse of the triangle. Then, according to the figure we have:
So:

Answer:
Step-by-step explanation:
Let's use the radius equation to a circle inscribed into a triangle.
In our case a = 13 mc, b = 13 cm and c = 10 cm
Then, s will be s = 18 cm
Then the radius will be:
Now, the distance from the vertex to the nearest touchpont is given by:
This value is the same for each side.
I hope it helps you!
