The keyword is "sum" which tells you x, y, and z are being added. One half of the sum means that the sum of the three numbers is going to be divided by 2.
x + y + z
------------
2
It would be e, because it went down 10 instead of 5
Answer: -7
Step-by-step explanation: x=3 and y=2
Answer:
x + 13 / x + 17
Step-by-step explanation:
x - 4 / x
x + 13 / x + 17
Answer:
105°
Step-by-step explanation:
Maps are usually oriented so that North is up. That means the southwest corner is below and to the left of the intersecting lines. Since numbered streets are usually parallel, we're to assume that W 22nd street is parallel to W 20th street. That makes Broadway a transversal of parallel lines, and it makes the angle of interest a corresponding angle to the one whose measure is shown.
In this (assumed) geometry, corresponding angles are congruent, so the angle of interest has measure 105°.
