The answer is c
(0,8) is the y intercept so the +.. is +8
then pug in 4 to x and find which one equal 0
<h3>
Answer: 140 degrees</h3>
==================================================
Explanation:
See the diagram below.
We start with triangle PQR with the given angles mentioned. Then you extend out segment QR to form line QR. It goes off infinitely in both directions.
The exterior angle x adds to the interior angle Q = 40 to get 180
x+40 = 180
x+40-40 = 180-40 ... subtract 40 from both sides
x = 140
The exterior angle is 140 degrees
Answer:
k=6
Step-by-step explanation:
18=k+12
you need to isolate k so you subtract 12 from both side
6=k
