Answer:
35/42 = b/7 and b= 35/6
Step-by-step explanation:
Our base is unkhown so it will be the variable in our equation :
- Let A be the area , h the height and b the base
- A = b*h
- 35/42 = b/7 this is the equation , let's solve it
- (35*7)/42 = b
- (35*7)/ 7*6 =b
- 35/6 = b
so b is 35/6 cm

Step-by-step explanation:
Assuming tan = 2
(

,
tart off by rewriting tan

(

) in to its sin
(

) and cos
(
x
) components.

Next find a common denominator

Combine in to a single fraction and factor out a

2
(

Finally just rewrite sin
2
(

Add up the amount of miles she actually reached to
2.4 + 3.1 =
5.5 = miles already traveled
And then subtract it from the 8 mile trail
8 - 5.5 =
2.5 miles
About 2.5 or 3 miles (rounded to the tenth or whole number?)
10 is that rule and 5 is the other rule
