Find the change in temperature from - 1 f to - 20 f

-19 F

Step-by-step explanation:

Change in temperature is simply the final temperature - initial temperature

in this case, final temperature is -20F and initial temperature is -1F

Change in temperature,

= Final temp - Initial temp

= -20 - (-1)

= -20 + 1

= -19 F

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
