Answer:
Hi there!
The answer to this question is c=23, b and d=157
this is because c is the vertical angle of a meaning the values are equal
and b is the supplementary angle to a: all you do is subtract 23 from 180 to get 157.
b is vertical to d, so d is also 157
Answer:
1235

Answer:
m∡ZA = 51°
m∡ZB = 39°
Step-by-step explanation:
∡ZB = 'b'
∡ZA = '12 + b'
b + 12 + b = 90
2b + 12 = 90
2b = 78
b = 39
12 + 39 = 51
I'm gonna do this 2 ways because I'm not sure what you mean about the line. I'm going to indicate greater than or equal to with >=.
1st I'll solve for
r/15 >= -3
multiply by 15 on each side
r >= -45
Next I'll solve for
r/15 >= 3
multiply 15 on each side
r >= 45
So depending on if that is a 3 or -3 that is how you would do it....
So did I read the problem right?
The answer for the equation is 21
