The sum of two numbers is 46 and their
difference is 20. What is the smaller
number?

x = 33

y = 13

okay

Step-by-step explanation:

let the numbers be x and y

given :

x + y = 46

x - y = 20

by adding both equations

=》x + y + x - y = 46 + 20

=》2x = 66

=》x = 66 / 2

=》x = 33

by putting the Value of x in 1st equation

=》x + y = 46

=》33 + y = 46

=》 y = 46 - 33

=》 y = 13

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

77
