The first one seems more reasonable
Angle STR = 28 (since this angle is equal to SRT = 28)
Angle STU = 2x
The two angles STR and STU form a straight angle. They are supplementary. This means they add to 180 degrees
(angle STR) + (angle STU) = 180
28 + 2x = 180 .... substitution property
2x + 28 = 180
2x + 28 - 28 = 180 - 28 ... subtract 28 from both sides
2x = 152
2x/2 = 152/2 ... divide both sides by 2
x = 76
Answer: (b) 76
Just graph it, that’s way too much work to do mentally.
Answer:
y = -(5/7)*x + 51/7
Step-by-step explanation:
First lets calculate the slope of the line passing through the points (-3,4) and (4,-1). This slope will be the same to the line that passes through (-1,8) since they are parallel. Finally we will determine the equation of the line which passes through that point.
m= (-1-4)/(4-(-3)) = -5/7
y-8/(x-(-1)) = -5/7
y-8 = (-5/7)*x -5/7
y= -5/7 *x - 5/7 + 8
y= -5/7 *x -5/7 + 8 = -5/7 *x + ((56 -5)7) = -5/7 * x + 51/7
None of the above is true
