To draw and label the diagram of the window and to find out the sides of the window and classify it.
Answer to Problem 19E
The length of the sides of the window measures 33inches,54inches and 54 inchesrespectively.
The window is of the shape of an isosceles
Explanation of Solution
Given information:
Ratio of the side length measures in a triangle is given as
Perimeter of the triangular window is given as 141 inches
Calculation:
Let the side measures be 11x, 18x, 18x.
The perimeter of the window is given as 141 inches. Hence,
Adding all the xtogether,
Divide both the sides by 47
This will give the value of
Hence the side measures are
First side is 11x so , multiply 11 with 3
Second side and third side are same as 18x, so multiply 18 with 3
The window is an isosceles triangle
Conclusion- The side of the length measures of the triangle are 33inches,54inches and 54 inches respectively.
As can be seentwo sides of the triangle is same and one is different, the shape of the window is of an isosceles triangle.
