Answer:
1. A = 59
2. A = 43
Step-by-step explanation:
If we have a right triangle we can use sin, cos and tan.
sin = opp/ hypotenuse
cos= adjacent/ hypotenuse
tan = opposite/ adjacent
For the first problem, we know the opposite and adjacent sides to angle A
tan A = opposite/ adjacent
tan A = 8.8 / 5.2
Take the inverse of each side
tan ^-1 tan A = tan ^-1 (8.8/5.2)
A = 59.42077313
To the nearest degree
A = 59 degrees
For the second problem, we know the adjacent side and the hypotenuse to angle A
cos A = adjacent/hypotenuse
cos A = 15.3/21
Take the inverse of each side
cos ^-1 cos A = cos ^-1 (15.3/21)
A = 43.23323481
To the nearest degree
A = 43 degrees

Answer:
Answer is <em>900</em>.
Step-by-step explanation:
To find:
Increase #500 in the ratio 16:10
Solution:
<em>New Number: Old Number = 16:10</em>
We are given the old number as 500.
Let the new number after increase = 
Now, using the above ratio:
<em /><em>: </em>500<em> = </em>16:10
Therefore, the increased value of 500 in the ration 16:10 is <em>900</em>.

x<-4
Hope it helped!
Distance d is directly proportional to time t that he rides.
So d = kt where k is the constant of proportionality
Here k = his speed = 20 mph
So the required equation is d = 20t
