They must equal 180°. Supplementary angles equal 180°
Answer:
60
Step-by-step explanation:
If angle 1 is 120 that means angle 5 is 120 too. Two angles together must equal 180 degrees.
Answer:
1).
= (200 -
)
2). Inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
Step-by-step explanation:
Function representing the maximum heart rate is,
f(x) = 0.85(220 - x)
Here x = age of the client
Equation form of the function will be,
y = 0.85(220 - x)
To get the inverse of the given function, replace 'x' by 'y' and 'y' by 'x' and solve for y.
x = 0.85(220 - y)
220 - y = 
y = 220 - 
Now convert this equation into a function.
= (200 -
)
Here inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
