Let the unknown angle be x.
That is
sin x = 4/5
cos x = 3/5
By drawing a right triangle in the first quadrant,
hypotenuse = 5
Adjacent side = 3
opposite side = 4
That is tan x = 4/3
From the calculator,
x = arctan(4/3) = 53 deg (nearest integer)
Answer: 53 deg. (nearest integer)
Answer:
$310.00 is the monthly payment if the phone was used for a total of 2,500 minutes.
Step-by-step explanation:
Since 500 minutes gets $62.00, we can multiply both to get 2,500 minutes, and $310.00.

The y-intercept would represent the highest point. The graph will show a parabola and this point will only be reached once.
The x-intercept would be the starting point and the ending point. You can find total distance traveled with this.
Answer:
Slant height (s)= 12.1 cm
Step-by-step explanation:
Given: Base= 4.5 cm.
Surface area of right square pyramid= 129.5 cm.
First, calculating slant height (s) of right square pyramid.
Surface area of square pyramid= 
a= side of square base.
s= slant height
∴ 
⇒ 
⇒ 
Now, opening the parenthesis and subtracting both side by 20.25.
⇒ 
cross multiplying both side
∴ Slant height (s)= 12.1
