Answer:
a equals 105°
Step-by-step explanation:
angles in a straight line add up to 180°
a+75=180
a=180-75
a=105°
Bse is 10
x^m, x is base of exponent
Given:
The graph of a function.
To find:
The range of the given function using interval notation.
Solution:
Range: The set of y-values or output values are known as range.
From the given graph, it is clear that the function is defined for
and the values of the functions lie between -2 and 2, where -2 is excluded and 2 is included.
Range 
The interval notation is:
Range ![=(-2,2]](https://tex.z-dn.net/?f=%3D%28-2%2C2%5D)
Therefore, the range of the given function is (-2,2].
9/11=x/22
11*2=22
9*2=x
x=18
9/11=18/22
