The answer is :
so, type 190 in the box
Step-by-step explanation:
Notice that there are three right angle triangles in the image given. In order to create equations associated with the Pythagorean Theorem for the three triangles, we add the letters x and z to identify two sides that are missing information. Please see attached image for reference.
In the small right angle triangle on the right, the Pythagorean theorem tells us:
In the larger triangle :
In the small triangle on the left:
and in this last equation we can substitute the z-squared and the x-squared by the expressions we got before in the other two equations:
Then to solve for "y" we apply the square root:
The age of Kwaku is 8 years old , Esi is 13 years old and Kojo is 26 years old.
<h3>What is an Equation ?</h3>
An equation is a statement that contains algebraic expressions equated by an equal sign with constants or other variables.
Let the age of Kwaku is x
Let the age of Esi is y
From the given data
The age of Kojo is 2y
y = x +5
Sum of their age = 47
2y = 2x +10
therefore the equation formed is
x + y +2y = 47
x + x+5 + 2x +10 = 47
4x +15 = 47
4x = 32
x = 8
y = 13
2y = 26
Therefore Kwaku is 8 years old , Esi is 13 years old and Kojo is 26 years old.
