Step-by-step explanation:
using trig, tangent is equal to opposite over adjacent.
in this case, the angle is 45, opposite is 7, and adjacent is a.
thus tan 45° = 7/a
solve for a to get a = 7/tan 45° = 4.32
You've already correctly labeled everything you need.
-- Ignore the lines YZ and YT .
-- That leaves you with the right triangle XYW .
-- Its legs are 8 and (12+3) = 15 .
-- XY is its hypotenuse.
I'm SURE you can finish it off from here.
Answer:
Step-by-step explanation:
Let
x -----> the number of ice cream cones sold 5 years ago
Remember that
we know that
Sales 5 years ago, multiplied by the 30% increase should equal 18,000 ice cream cones.
so
The linear equation that represent this problem is
Solve for x
Divide by 1.3 both sides
