Answer:
x= 27
Step-by-step explanation:
a triangle always has 180 degrees, therefore:
(3x-17)+(x+40)+(2x-5)= 180
6x+18=180
6x=162
x=162/6
x=27

Answer:
Part a) 
Part b) 
Step-by-step explanation:
Part a) Create a linear equation
Let
t ----> the time in minutes
y ---> the temperature in °F
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem we have
The slope m is equal to

The y-intercept is

substitute

Part b) How many minutes until the water boils at 212° F?
For y=212° F
substitute in the linear equation and solve for t
