Answer
a) Angle NMP = 58°
b) Angle NMP = 60°
Step-by-step explanation
We are told that Angle NMQ is a right angle, meaning that Angle NMQ = 90°
a) Angle PMQ = 42°, what is Angle NMP?
From the image, we can tell that
(Angle NMQ) = (Angle NMP) + (Angle PMQ)
90° = Angle NMP + 42°
Angle NMP = 90° - 42° = 58°
b) If Angle NMP is twice Angle PMQ, find Angle NMP.
Let Angle PMQ = x
Then Angle NMP = 2 (Angle PMQ) = 2x
From the image, we can tell that
(Angle NMQ) = (Angle NMP) + (Angle PMQ)
90° = 2x + x
90° = 3x
3x = 90°
Divide both sides by 3
(3x/3) = (90°/3)
x = 30°
Therefore, Angle PMQ = x = 30°
Angle NMP = 2 (Angle PMQ) = 2 (30°) = 60°
Hope this Helps!!!
