Answer:
8606.4 Miles
Step-by-step explanation:
Since we know that each lap was the same length, we can do 137,702.4/16 and get 8606.4
Answer:5
That is exactly correct! Just two things: First, tan,sin,cos, etc hold no meaning on their own, they need an argument. So just be sure to write tanx, cosx etc rather than just tan or cos.
Finally, you could save time on your proof by noticing on the fourth step that
1cosxsinx=1cosx1sinx=secxcscx

Step-by-step explanation:
Triangle area formula= bh/2
Blue triangle:
10*12/2= 60
Orange triangle:
8*10/2= 40
Add the values: 40+60= 100 in^2
Final answer: 100 in^2
C: SAS
Step by step:
The first side is the side that was already established is the same as the other (ab & bc) The angles from point b are congruent because it’s an isosceles triangle so the mid point of the base is the altitude of the triangle and angle bisector of the angle opposite of it. Since it’s an angle bisector both are equal. The third side is the one that they share (bd). Then using SAS you can prove congruency.
Hope that helps :)
