since the triangle is right use the tangent ratio to solve for x
∠a = 180° - (90 + 40)° = 180° - 130° = 50°
tan50° = =
multiply both sides by 8
x = 8tan50° → b
go up the y-axis starting from (0,0) by 8 points.
then make 2x a fraction, x
then "rise" or go up 2 points, then "run" or go to the right one point.
which should get you (1,10)
multiply 80 * 24, to get the total amount sold each day. divide by 10 to get the amount per hour.
we are given the following expression and we are to simplify it leaving the answer in the form of an improper fraction:
we will start by adding the first two fractions by taking their lcm and making it a single fraction to simplify the expression further:
now subtracting from the result obtained above:
12 2/5 - 5 1/10
a.) 7 1/...
