It's an isosceles triangle, so the angles at the base are congruent:
The triangle XYW is a rectangular triangle.
We know that the sum of the measures of angles in a triangle is 180°.
Therefore we have the equation:
Answer: 73
In the diagram below, BD is parallel to XY. What is the value of x?

Answer:
Cameron’s solution is unreasonable because 17 times 9 is 153, and 153 is not close to his product.
Step-by-step explanation:
Area of a rectangle:
The area of a rectangle, of length l and height h, is given by:
The length of a rectangular wall is 16.5 feet. The height of the wall is 8.625 feet.
This means that
Estimate of the area:
To use an "easy" multiplication, lets consider . So
Cameron determines the area of the wall to be 1423.125 square feet.
Very far from the area of 153, which means that he made a confusion with the decimal places. Thus, the correct answer is:
Cameron’s solution is unreasonable because 17 times 9 is 153, and 153 is not close to his product.

[surface area of the composite solid]=1*(4*6)+2*(4*4)+2*(4*6)+2*(4*√13/2)+2*(6*2√2/2)
[surface area of the composite solid]=24+32+48+4√13+12√2
[<span>surface area of the composite solid]=135.39 yd</span>²
the answer is
135.39 yd²
[surface area of the composite solid]=1*(4*6)+2*(4*4)+2*(4*6)+2*(4*√13/2)+2*(6*2√2/2)
[surface area of the composite solid]=24+32+48+4√13+12√2
[<span>surface area of the composite solid]=135.39 yd</span>²
the answer is
135.39 yd²
