Answer:
x = 99 degrees.
Step-by-step explanation:
The angle in the triangle adjacent to 123 = 180 - 123 = 57 degrees.
m < x = 42 + 57 = 99 degrees. ( by the external angle of triangle theorem).

DDDDDDDDDDD
Step-by-step explanation:
Just took the quiz on Edge
Y =2x +14
-4x –y = 4 so y = -4x – 4
2x + 14 = -4x – 4
2x + 4x = -4 - 14
6x = -18
x = -18/6
x = -3
Y =2x +14
y = 2(-3) +14
y= -6 +14
y=8
answer:
y-coordinate is 8
The value (y2) of r = 1/2.
This question relates to equation of a straight line but we are looking for the slope in this case.
<h3>Slope</h3>
This is the ratio to which we measure the change along the y-axis to the change along the x-axis. The formula is given as

Data given;
- x1 = 3
- x2 = -3
- y1 = 5
- y2 = r
- m = 34 or 3/4
Substitute the values into the equation and solve for the unknown
NB; we are assuming that the slope here is 34 and not 3/4.

cross multiply both sides and make r the subject of formula

the value of r = -199.
This is not mathematically obtainable and we would use 3/4 as the value of slope

The most logical value of r = 1/2
