No it is NOT possible - that would mean the final angle would also have to be ninety degrees making it a square or rectangle. :)

sukhopar [10]
We know that

Right triangles PBM and MTF are similar 
because
angle PMB=angle TMF
and
angle BPM=angle FTM
and 
angle B =angle F=90 degrees
so
corresponding sides are
BM and MF
PB and TF
PM and MT
(PB/TF)=BM/MF
solve for PB
PB=(TF*BM)/MF
where
TF=6ft
BM=20 ft
MF=3 ft
so
PB=(6*20)/3------> 40 ft

the answer is
<span>the height of the peak is 40 ft</span>

Consider a bag that contains 218 coins of which 6 are rare Indian pennies. For the given pair of events A and​ B, complete parts
Afina-wow [57]

Answer: (a) Independent events , (b) 0.00075

Step-by-step explanation:

Since we have given that

Number of coins = 218

Number of rare Indian pennies = 6

Let Event A: When one of the 218 coins is randomly​ selected, it is one of the 6 Indian pennies.

Event B :  When another one of the 218 coins is randomly selected​ (with replacement), it is also one of the 6 Indian pennies.

As we know that

P(A)=\dfrac{6}{218}=0.0275\\\\and\\\\P(B)=\dfrac{6}{218}=0.0275

(a) so, they are independent events as there is a condition of 'with replacement'.

(b) P(A and B) is given by

P(A\cap B)=P(A).P(B)=0.0275\times 0.0275=0.00075

Hence, (a) Independent events , (b) 0.00075
