solniwko [45]

Answer:

Minimum temperature is 68.5 ° and maximum temperature is 76.5 °

Step-by-step explanation:

Given :

|x – 72.5| = 4.

When the Temperature of x is minimum So the Minimum temperature is

$|x - 72.5| = 4\\it\ can \ be \ written \ as \\72.5-x=4\\-x=4-72.5\\x=68.5$

When the Temperature of x is maximum So the Maximum Temperature is

$|x -72.5| = 4\\x-72.5=\ 4\\x=72.5+4\\x=76.5$

Therefore The minimum temperature is 68.5 ° and the maximum temperature is 76.5 °

Find the measure of x

From the attached image:

$11x + 2$ and $-2 + 7x$ form a semi-circle

So:

$11x + 2 -2 + 7x = 180$

Collect like terms

$11x + 7x = 180+ 2 -2$

$18x = 180$

Solve for x

$x = \frac{180}{18}$

$x = 10$
