Answers:
x = 57
y = 86
z = 37
=================================================
Work Shown:
x+123 = 180 .... since x and 123 form a straight line
x = 180-123
x = 57
y = 86 since the y and 86 angles are vertical angles
-------
For any triangle, the three angles always add to 180. So,
x+y+z = 180
57+86+z = 180
143+z = 180
z = 180-143
z = 37
As a check,
x+y+z = 57+86+37 = 180
which confirms the value of z

Answer:
198
Step-by-step explanation:
2(9)(11)
Since you know that r = 9 and t = 11, you can substitute the variables to numbers. Then you just multiply to get 198. Hope this helps :)
To get the *percent increase* from week 1 to week 2, we calculate the change in distance from week 1 to week 2 (13.5 - 12.5 = 1 mile) over the week 1 distance (12.5 miles). Doing that, we find that Matthew increased his distance by
1/12.5 = 0.08, or 8%
We’re given that he’ll increase his distance by the same percentage from week 2 to 3, so to find his week 3 distance, we can find 8% of the week 2 distance and add that on. 8% of 13.5 miles is 0.08 x 13.5 = 1.08 miles, so by week 3, he’ll be running 13.5 + 1.08 = 14.58 miles.
