Answer:
im not sure wish i could help
Step-by-step explanation:
This question we do not have to over think. We can already answer this with out the help of the diagram. The diagram helps us see that this problem involves the number line. Positive and negative numbers are involved in the number line.
Here how we can think about it: From the middle to the left the length is 39 and to the right it is 19. The length is then 58.
A rate in which the numerator and the denominator are equal to a rate of one
The cool thing with angles, is that the angle corresponds to the length of the side it's facing. With this, we know that angle B causes a side length of 9; just as well, it is 45 degrees. It also just so happens that angle A is 45 degrees as well. This means that side Y is 9 units long as well.
Now for side X!
We can use the Pythagorean Theorem for this:
X^2=9^2*9^2
X^2=81+81
X^2=162
Now we square root to find:
X=12.73
I hope this Helps!
