Answer:
4th Option
Step-by-step explanation:
When we look for side <em>x</em>, we have multiple ways:
cos60° = 10/x
x = 10/cos60°
sin30° = 10/x
x = 10/sin30°
sin60° = 15/x
x = 15/sin60°
cos30° = 15/x
x = 15/cos30°
Out of these choices, only the 4th Option is present, so that is our answer.
A. The expression to represent the elevation of city D is 1/2 × 12.
B. Solving the expression, 1/2 × 12 = 6 ft the elevation of city D is positive because the elevation of city D is above sea level.
The elevation of city A is 60 ft above sea level .
The elevation of city C is 12 ft above sea level.
The elevation of city D is 1 /2 of the elevation of city C. Therefore, the elevation of city D above sea level will be
A.
The expression to represent the elevation in feet of city D is as follows:
B.
Let's solve the expression below:
The answer is positive because the elevation of city D is above see level.

Answer:
The 2 numbers are -12.5 and 17.5.
Step-by-step explanation:
Let 1 number be x then x - y = 30 where the other number is y.
y = x - 30 so the sum is:
x - 30 + x = 5
2x = 35
x = 17.5
and y = 17.5 - 30 = -12.5.
Thinking it’s A! Sorry if I’m wrong! :)
