1x1 = 1 !!
Hope this helped.
Irrational kind of means something can't be dealt with, for example, you cannot divide irrational numbers. Rational is something that you can do and will be good to work with, you can divide rational numbers.
it would be b or c depending on a's number
I hate Time4Learning. I took that back in middle school.
Here's how these expressions work together. First, you need to remember WZY is a right angle (90 degrees). Now, keep that in mind when we add both equation.
3c + 2c + 2 - 7 = 90
5c - 5 = 90
5c - 5 + 5 = 90 + 5
5c = 95
5c/5 = 95/5
c = 19. Now, put 19 in the place of c and solve.
3(19) + 2 = 57 + 2 =
59 degrees.
The measurement of angle WZX is equal to 59 degrees, B.
