Step-by-step explanation:
a = m - n
or
m = a + n
or
n = m - a

Step-by-step explanation:
Answer:
The last pair are vertical.
Step-by-step explanation:
Hey there! :D
Pay attention to the given angles.
We know that a circle is equal to 360 degrees.
We know two angles, and the other 2 are the same measure.
170+44= 214
Subtract that from 360, since that is what the circle equals.
360-214= 146
Divide that by two, since there are 2 equal angles left.
146/2= 73
<DOB= 73 degrees.
You were correct, so good work!
I hope this helps!

Answers:
- x = 21.25
- y = 22.5
- z = 23.75
=============================================================
Work Shown:
AP = arithmetic progression, which is the same as arithmetic sequence
d = common difference
- x = 20+d
- y = 20+2d
- z = 20+3d
Notice how we scale up the d terms d, 2d, 3d, counting up by 1 each time.
So that must mean 25 is the same as 20+4d
20+4d = 25
4d = 25-20
4d = 5
d = 5/4
d = 1.25
and therefore,
- x = 20+d = 20+1.25 = 21.25
- y = 20+2d = 20+2*1.25 = 22.5
- z = 20+3d = 20+3*1.25 = 23.75
We could convert these to fraction form, but I find decimal form is easier in this case.
