Answer:
Step-by-step explanation:
- <em>Refer to attached diagram</em>
<h3>Given </h3>
- MN = NQ
- MQ = QR = RP
- NMR = 3x
- QMR = x
<h3>To find</h3>
<h3>Solution</h3>
- MN = NQ ⇒ ∠MRN = ∠QMN = 3x+x = 4x
- MQ = QR ⇒ ∠MRQ = ∠QMR = x
<u>RQP is exterior angle of ΔMQR ⇒ </u>
<u>QR = RP ⇒ </u>
<u>∠QRN is exterior angle of ΔQRP ⇒ </u>
- ∠MRN = ∠QRN - ∠QRM = 4x - x = 3x
<u>∠MRN = ∠NMR = 3x ⇒ </u>
<u>NR = MQ ⇒ </u>
<u>We now have a straight angle MQP:</u>
- ∠MQP = ∠MQN + ∠RQN + ∠RQP
- 180° = 4x + 4x + 2x
- 10x = 180°
- x = 18°
Correct choice is C

See below.
Step-by-step explanation:
Helen made a mistake in the last step.
2^(4/3) / e = (∛(2^4) / e = ∛(16) / e .
It is the cube root of 2^4 not the 4th root of 2^3.
Stephen made a mistake in the first step.
He replaced ln2 by 2 which is evidently wrong (e^ln2 = 2 NOT ln 2).
