Answer:

Sample Response: First, identify the longest length, the square root of 186, as the hypotenuse. Find the squares of each side. For the roof, the sum of the squares of the two shorter sides, 186, equals the square of the longest side, 186. Yes, the roof is a right triangle.

We know that 

[the area of the root]=4*[area of one lateral triangle side]

area of one lateral triangle side=b*h/2
b=10 ft
h=9.4 ft
area of one lateral triangle side=10*9.4/2-----> 47 ft²

[the area of the root]=4*[47]-------> 188 ft²

the answer is
the area of the root is 188 ft²

Aleksandr-060686 [28]

Answer:

There may be 1 or 3 tricycles in the parking lot.

Step-by-step explanation:

Since at any point in time, there could be bicycles, tricycles, and cars in the school parking lot, and today, there are 53 wheels in total, if there are 15 bicycles, tricycles, and cars in total, to determine how many tricycles could be in the parking lot, the following calculation must be performed:

13 x 4 + 1 x 3 + 1 x 2 = 57

11 x 4 + 1 x 3 + 3 x 2 = 53

10 x 4 + 3 x 3 + 2 x 2 = 53

8 x 4 + 5 x 3 + 2 x 2 = 51

10 x 2 + 1 x 3 + 4 x 4 = 39

9 x 3 + 1 x 2 + 5 x 4 = 49

Therefore, there may be 1 or 3 tricycles in the parking lot.
