First, find out how many messages are received a second. Do this by dividing messages by 60 seconds.
120/60 = 2 messages a second
now multiply 2 by 150
2*150 = 300messages in 150 seconds
your answer is (3) 300
Answer: b
Step-by-step explanation:
Prove
m∠5+m∠2+m∠6=180°
we have that
m∠1+m∠2+m∠3=180° equation I
m∠1=m∠5 -------- > in<span>ternal alternate angles equation 2
</span>
and
m∠6=m∠3-------- > internal alternate angles equation 3
<span>I substitute equation 2 and equation 3 in equation I</span>
m∠1+m∠2+m∠3=180°-------- > m∠5+m∠2+m∠6=180°------- > is ok
