90°is the answer because 90°+90°=180°
The answer to your question is 300,000
White as system of equations:
a=(3,-2) b=(1-1)
{a=1-1
{(3-2)b=1-1
Solve the equation for a:
{a=0
{(3-2)b=1-1
Solve for B :
a=0
b=0
The possible solution to the system is the ordered pair ( a , b )
Solution:
( a , b )= ( 0 , 0 )
There you have your answer :)
Given:
Consider the given expression is:

To find:
The simplified form of the given expression.
Solution:
We have,

By using the quotient property of exponents, we get
![\left[\because \dfrac{a^m}{a^n}=a^{m-n}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbecause%20%5Cdfrac%7Ba%5Em%7D%7Ba%5En%7D%3Da%5E%7Bm-n%7D%5Cright%5D)


By using negative exponent property, we get
![\left[\because a^{-n}=\dfrac{1}{a^n}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbecause%20a%5E%7B-n%7D%3D%5Cdfrac%7B1%7D%7Ba%5En%7D%5Cright%5D)
The simplified form of the given expression is
.
Therefore, the correct option is B.
