Answer:

Sum of the angles of the triangle is 180°.

=> 39° + 4y + y + 11° = 180°

=> 5y + 50° = 180°

=> 5y = 180° - 50°

=> 5y = 130°

=> y = 130°/5

<h3>=> y = 26°</h3>

Answer:

Sum of the interior angles of the triangle is 180°.

According to the above problem,

4y + (y + 11) + 39 = 180 \\ 5y + 50 = 180 \\ 5y = 130 \\ y  = \frac{130}{5}  \\  \boxed{y = 26}✓

<h3><u>y=26</u><u>°</u> is the right answer.</h3>

Use the layout of the parking lot to answer the questions. what is the total area available for cars to park? m2. if the parking
s344n2d4d5 [400]

The true statements are:

  • The total area available is 858 square meters
  • The number of compact parking space is 68
  • The number of non-compact parking space is 52

<h3>The total area available for cars to park</h3>

From the complete question, we have the dimensions of the parking lot to be: 78 meters by 19 meters

Also, the dimension of the aisle is: 8 meters by 78 meters

The total parking area is the difference between the parking lot area and the aisle area

This gives

Parking Area = 78 * 19 - 8 * 78

Parking Area = 858

The total area available for cars to park is 858 square meters

<h3>The number of parking space</h3>

The number of parking lot is the quotient of the total parking area and the area of each compact

So, we have:

n = 858/12.5

n = 68.64

Remove the decimal

n = 68

Hence, the number of parking space is 68

<h3>The number of parking space for non-compact parking space</h3>

The number of parking lot is the quotient of the total parking area and the area of each non-compact space

So, we have:

n = 858/(5.5 * 3)

n = 52

Hence, the number of parking space is 52

the length of one leg of a right triangle is 20ft, and the length of the hypotenuse is 52 ft. What is the length of the other le
Dima020 [189]
A^2 + b^2 = c^2
20^2 = 400
52^2 = 2704
400 + b^2 = 2704
2704 - 400 = 2304
So you need the square root of 2304 which is 48 so the length of the other leg is 48 ft.
