The answer is 75
First you subtract 180 and 165 to find that smallest angle inside the triangle(15). Then you add 15 and 90,the two angles you know, and do 180 - 105= 75.
The trick is that all angles inside a triangle equal 180 degrees. Hope this helps!

Answer:
The temperature of the chemical solution after t hours is 
Step-by-step explanation:
Given that the initial temperature of the chemical solution,
.
The rate of decreasing temperature, 
So, after t hours, the temperature of the chemical solution will decrease by
.
So, the temperature of the chemical solution after t hours,

Hence, the temperature of the chemical solution after t hours is
.
Point slope give a point on the line and the slope
it is best used when you are given a point on the line and the slope
or
it is also good when you knwo how to find the slope and you are given 2 points
