Answer:
C
Step-by-step explanation:
The area of a circle is pi * r^2. The radius is 7 because the diameter is 14 so the radius is 14/2. The square of 7 is 49. Pi is approximately 3.14, so 49 * 3.14 is about 154.
Answer:
169
Step-by-step explanation:
7 + 6 = 13
13² = 169
hope this helps
Answer:
yoiu do the firdtone then the poopholestep explanation:
420 69
Cot A=1/tan A=12/5
cos A= 12/13
sin A=5/13
Draw a right angled triangle
the hypotenuse is the longest side which is 13 using Pythagoras theorem
the side opposite the angle A is 5
the side closest to the angle A which is called the adjacent is 12
sinA =opp/hyp
cos A= adj/hyp
cotA =1/tanA=cos A/sinA
Note: Pythagoras theorem is
hyp²=opp²+adj²
Answer:
The correct answer is: 
by <em>rule</em> ASA rule of congruence.
Step-by-step explanation:
First let us prove by rule ASA (rule of congruence).
<u>Congruent side:</u>
(Given)
<u>Congruent angles:</u>
1. By definition of perpendicular,
Also,
Therefore,
or you can say,
2. Common angle between 
is 
In a nutshell, in 
,
(Angle)
(Side)
(Angle)
are congruent to the following angle, side and angle of 
:
(Angle)
(Side)
(Angle)
Therefore, by ASA rule of congruence, we can say .
<em>Since both triangles are congruent</em>, the sides 
and 
are also congruent.
