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
If this is just a question to simply this equation, then here's the answer.
-10 + 4n -3t +2t +n
First, add together the n's: 4n+n = 5n
Then, the "t's": 2t - 3t = -t
Since there are no other numbers, you have:
-10 + 5n - t
