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
Point ‘N’ would be a reflection across the Y-Axis
It is true since you’re multiplying the same number on both the sides
You have to say what or where point B and C is for me to answer it
