Rectangle because in a triangle you have to multiply by 1/2
I thought that was all one equation lol this is very simple just plug in -3 for x
which is -3^2-3 which is -12
Answer:
x = 12
Step-by-step explanation:
The total of all the angle is 180 degrees so just divide 180 by the total number of x's which is 5+4+3+2+1 = 15
180/15 = 12
If you wanted to know how much each angle is just plug in 12 for x.
So first angle is just X so it is 12 degrees.
Second angle is 2X so 2x12 = 24 degrees.
and so on for all the angles.
It is given in the question that the end of a pendulum with a length of 21 cm travels an arc length of 24 cm.
So here radius is 21 cm and the arc length is 24 cm .
Now we use the arc length formula , which is

Where s is the arc length and r is the radius.
Substituting these values, we will get

And now we need to convert radian to degree, and for that we have to multiply by 
That is
