<h3><em><u>SOLUTION:</u></em></h3>The image of the question is attached below.
Given each unit length = 1 foot
Tile cost per square feet = $1. 65
To find the area, split the floor shape into two shape.
One is trapezoid and the other is parallelogram.
Let's count the grid given.
The parallels sides of trapezoid are 7 ft and 4 ft, height is 7 ft.
The base and height of the parallelogram are 4 ft and 4 ft respectively.
Area of the trapezoid =1/2 ×(sum or parallel sides)× height
=1/2× (7+4)×5
=1/2×11×5
Area of the trapezoid = 27.5 sq.ft
Area of the parallelogram = base × height
= 4 ft × 4 ft
Area of the parallelogram = 16 sq. ft
Total area = 27.5 sq. ft + 16 sq. ft
= 43.5 sq. ft
Cost of area per sq. ft = $1.65
Cost of area 43.5 sq. ft = 43. 5 × 1.65
= $71.775
= $71.78
Hence Sal will pay $71.78 to tile his entryway.
<h3><u>Answer</u><u>:</u><u>-</u></h3>
x=17
<h3><u>step-by</u><u>-</u><u>step</u><u> </u><u>Explanation</u><u>:</u><u>-</u></h3>This is a isosceles triangle. As it is a triangle we can apply sum theory. we have to take the sum of given unknown polynomials as 180° .Then by solving it we can find the value of x.
<h3><u>Solution</u><u>:</u><u>-</u></h3>Given angles
- (6x+10°)
- (x+17°)
- (4x-34)°
According to sum theory
- Substitute the values
- Remove brackets
- Together like polynomials and constants
- Interchange sides
- Simplify
