Answer:
Step-by-step explanation:
1). Since angles P and Q are supplementary,
m∠P + m∠Q = 180°
(5x + 3)° + (x + 3)° = 180°
6x + 6 = 180
6x = 174
x = 29
Therefore, Option (3) is the answer.
2). If a point P lies in the interior of ∠RST,
m∠RST = m∠RSP + m∠TPS
(Since, line SP is bisector of angle RST)
m∠RST = 40° + 10°
= 50°
Therefore, option (2) is the answer.
3). AB = distance between two points A and B on a number line
= 8 - (-12)
= 8 + 12
= 20
Therefore, length of AB = 20 units.
