Answer:
<em>52.5 Seconds</em>
<em></em>
Step-by-step explanation:
Let's call, her time for the third race, x.
To find the average (53.4), we add up all the values and then divide this total by the number of values.
So, we will set up our equation.
56.4 + 51.3 + x
> ------------------------ = 53.4
3
To get rid of 3, we will multiply both sides by 3.
> 56.4 + 51.3 + x = 160.2
> 107.7 + x = 160.2
We will subtract 107.7 from both sides to isolate x.
<h2>
> x = 52.5</h2><h2>

Answer:
m∠CAB = 40°
Step-by-step explanation:
DAC = 99
DAB = 59
B is inside DAC, and so is DAB. So CAB must add to 59 to get to 99, nothing over that because it's inside DAC.
So 99 - 59 = 40
CAB must be 40°
That's all I can say for now. Hope this helps and a thank won't hurt! :)
