Step-by-step explanation:
If the tens digit of the number is X and the ones digit is Y then the number is equal to 10*X + Y
If you reverse the digits then the number is equal to 10*Y + X
If reversing the digits decreases the number by 36 then
10*Y + X = 10*X + Y - 36
The sum of the digits is 4 so X + Y = 4 ==> X = 4 - Y
Substitute this value of X into the 1st equation
10*Y + (4 - Y) = 10*(4 - Y) + Y - 36
9*Y + 4 = 40 - 9*Y - 36
18*Y = 0
Y = 0
I hope it helps you
So X = 4 - 0 = 4 and the number is 40
so, let's check 40 - 04 = 36

Complete question
<em>A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid 90.1. What is the height of the pyramid?</em>
To get the height of the pyramid, we will use pythagoras theorem.
slant height l is the hypotenuse
length of the base is the adjacent
height of the pyramid is the opposite
According to the theorem;
l² = h² + b²
90.1² = h² + 89.6²
8,118.01 = <em>h²+</em>8,028.16
h²= 8,118.01 - 8,028.16
h² = 89.85
h =√89.85
h = 9.48
Hence the height of the pyramid will be 9.48
<em>Note that the value of the slant height was assumed to solve the problem</em>.
