Answer: (b) exactly one plane contains a given line and a point not on the line.
Step-by-step explanation: The basic postulates of geometry are very-well known to all of us. For example-
(i) The intersection of two lines determines a point,
(ii) Two parallel lines give result to a plane,
(iii) A line and a point not on the line determines a plane, etc...
Thus, with the help of the third point, we can easily arrive at the conclusion that a given line and a point not lying on the line is contained in a plane. For example- see the attached figure, AB is a line and P is any point not on the line. They both contained in the plane ABC.
Hence, the correct option is (b).
<h2>Question:-</h2>
- Find the compound interest when
- principal =2000
- rate =20%per annum
- and time 3 years.
<h2>To find:-</h2>
<h2>Given:-</h2>
- Principal = Rs.2,000
- Rate = 20%
- Time = 3 years.
<h2>Solution:-</h2>
⇒
=
= 
= 
= 
= 16 × 6 × 6 × 6
⇒A = Rs.3456
⇒CI = A - P
⇒CI = 3456 - 2000
⇒CI = Rs.1456
Answer:-
·Compound interest is Rs.1456.
The y intercept is 9 and the unit rate is -7
So we plug these numbers in
y= -7x (the unit rate)+ 9 (y intercept)
y= -7x+9
The measure of angle 1 is (20-10)/2= 10/2= 5 degrees
Answer:
in triangle ACD and BCE
AC = EC
angle ACD = angle ECB ( COMMON ANGLE).
CB = CD
BY side and side criteria
triangle ACD is congruent to triangle BCE
so angle a is congruent to angle E
hence, proved
