Can someone please help me

Answer:

  1. 125 in²
  2. 676 km²
  3. 20 square units

Step-by-step explanation:

The Pythagorean theorem tells you the square on the hypotenuse is equal to the sum of the squares on the other two sides. (This is the version you use for problem 2.)

This also means the square on one side is the difference between the square on the hypotenuse and the square on the other side. (Use this version for problems 1 and 3.)

1. ? = 200 in² -75 in² = 125 in²

2. ? = 576 km² + 100 km² = 676 km²

3. ? = 36 square units - 16 square units = 20 square units

A department store sells small boxes in which customers can store potpourri. The diagram below shows one of the boxes. The diagr
larisa86 [58]
The lateral area is expressed as the product of the perimeter of the base and the height. While the surface area is the sum of all areas. The lateral area and the surface area of the box is calculated as follows:

LA = Ph 
P = 2l + 2w = (2 x 17) + (2 x 5) = 44 cm
LA = 44 cm x 3.12 cm = 137.28 cm

SA = 2(lw + wh + lh)
SA = 2[(17x5) + (5x3.12) + (17x3.12)]
SA = 307.28 cm

Thus, the lateral area and the surface area are 137 cm and 307 cm, respectively.

Please explain step by step
Alja [10]

Let's find the value of x

Since the sum of internal angles of a triangle is 180°

therefore,

\hookrightarrow \: (2x - 2) \degree + (x + 5) \degree + 90 \degree = 180 \degree

\hookrightarrow \: 2x - 2 \degree + x + 5\degree  = 180\degree - 90\degree

\hookrightarrow \: 3x + 3\degree = 90\degree

\hookrightarrow \: 3(x + 1) = 3(30)

\hookrightarrow \: x + 1\degree = 30\degree

\hookrightarrow \: x = 29\degree

I need a little help
user100 [1]

Answer:

A)  x = 8\sqrt{2}

Step-by-step explanation:

in a 45-45-90 triangle, the legs to hypotenuse ratio is 1 : \sqrt{2}

so in this problem the leg is 8 and the hypotenuse is 8\sqrt{2}
