Answer:
39°
Step-by-step explanation:
A radius of a circle (segment CD) drawn to the point of tangency (D) intersects the tangent (line DE) at a 90-deg angle.
That makes m<D = 90.
m<D + m<C + m<E = 180
90 + 51 + m<E = 180
m<E = 39
Answer:
<h2>BR ≈ 49.0</h2>
Step-by-step explanation:
Use cosine:

We have


Substitute:

<em>cross multiply</em>
<em>divide both sides by 8,572</em>


C.) obtuse Hope this helps!
Answer:
284
Step-by-step explanation:
You have to start out multiplying the (parentheses), then the [brackets], then the {curly brackets}. After you're done with those you would add 2.
So you have to isolate the variable c
to do so multiply both sides by 2
2*(6/15) = c
you can do the rest
Hope this helps ;)
