The computation illustrated shows that the numbers that can be used to get the sum of 42 will be 12 and 15.
<h3>How to compute the value?</h3>
It should be noted that the puzzle simply involves algebraic thinking. The goal is to find numbers that can be added together that will give 42.
From the information, it should be noted that 7 and 8 have been given. Therefore, this will be:
= 42 - (7 + 8)
= 42 - 15
= 27
Therefore, the numbers that can give 27 can be put in the box. An example is 12 and 15.

In your point, y is 3 and x is 2. You have to fill in these values for x and y into each equation in A-D to see which one is "true". Let's start with A. y = -3x. Filling in 3 for y and 2 for x gives us 3 = -3(2). Does 3 equal -6? Of course not. So let's try B. y = x - 1. 3 = 2 - 1. Does 3 = 1? Of course not! Let's try C. y = 3x...3 = 3(2). 3 doesn't equal 6 either, so...last one. y = x + 1 is 3=2+1. Does 3 = 3? Yes! Finally! So the point on the coordinate plane is one the line represented by D.
It is graph b, its negative
Distance of the person from the building (x)
tan 24 = 20/x => x = 20/tan 24 = 44.92 ft
The height of the building above the height of the person and the distance of the person from the building forms two legs of right angled triangle.
Therefore, if h is the height of the building, then;
tan 31 = (h-20)/44.92
h-20 = 44.92 tan 31
h = (44.92 tan 31) + 20 = 26.99 + 20 = 46.99 ft
