Answer:
Denote O as center of circle, draw OA, OC.
As property of tangent line from outside of circle (angle OAD = angle OCD = 90 deg):
=> AOC + D = 180
Moreover, angle AOC = 2 x angle B = 2 x 65 = 130
=> D = 180 - 130 = 50 deg
Hope this helps!

3 over 1 + 6 over 60
[3 over 1 × 60 over 60] + 6 over 60
180 over 60 + 6 over 60 ➡ 186 over 60
186 over 60 ➡ 31 over 10
Then we divide 31 from 10 which give you the quotient of 3.1..
(((Meaning ➡ '"3.1" would be your answer)))
That's the second one,
180 - x = r
Whenever two lines cross we get congruent opposite angles and supplemental adjacent angles, i.e. they add to 180 degrees.
The first one is almost right; we have r+y+z=180 and r+x=180 so x=y+z not quite what was written.
8p, -70, and 4 z are the terms and 4z and 8p are coefficient.
