Answer:
7374
0.
Step-by-step explanation:
a^r = a1 * r^(n-1)
So, the terms are:
2*(3)^(8-1) = 4374
and
0*(1/2)^-1/2 = 0
To do this problem you need to find angle adc which is a part of angle BDA. angle BDA is 90 degrees so the 2 parts must add up to 90 degrees so you set up the problem like this
-2x + 144 - 3x +51 =90
then you combine like terms
-5x +195 = 90
then you subtract 195 from 90
-5x = -105
then you divide -5 by -5 and -105 by -5 and get
x=21
then you plug x in and get your angle measure
-3(21) +51
then you get the angle measure as 114 degrees.
Yes, you are correct.
The two numbers you add to make twenty and have a difference of four are 12 and 8.
any point that is on the circle will have a distance of "radius" units, namely 13 units, since the radius is just that.
