Answer 1

The sum of the interior angles of any quadrilateral is 360°.

So,

90° + 90° + 52° + x = 360°

=> 232° + x = 360°

=> x = 360° - 232°

=> x = 128°

Answer 2

Answer:

x = 128

Step-by-step explanation:

All angles on a trapezoid must add up to 360 degrees. So we have 3 of our 4 angles so we can solve this as an equation

90 + 90 + 52 + x = 360

232 + x = 360

x = 128

What is the internal angle sum of a quadrilateral? (Hint: A quadirlateral has 4 sides.) OA) 90 OB) 180 OC) 360 OD 540

A.) 90°
B.) 180°
C.) 360°
D.) 540°​

Answers

The internal angle sum of a quadrilateral is :

C. 360°

The sum of internal angles of a polygon is determined by a formula :

[tex] \longmapsto (n - 2) × 180° [/tex]

where n represents number of sides.

In a quadrilateral there are four sides,

So, plugging 4 in the formula :

[tex](4 - 2) \times 180°[/tex]

[tex]2 \times 180°[/tex]

[tex]360°[/tex]

A triangular prism. The rectangular sides are 2 centimeters by 13 centimeters, 12 centimeters by 2 centimeters, and 5 centimeters by 2 centimeters. The 2 triangular sides have a base of 5 centimeters and height of 12 centimeters. Which equation could be used to find the surface area of the net of the triangular prism shown? SA = (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2) SA = (1/2) (5)(13) + (1/2) (5)(13) + (5)(2) + (13)(2) + (12)(2) SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2) SA = (2)(5)(13) + (5)(2) + (13)(2) + (12)(2)

19. When baking a cake, you have a choice of the following pans:
1. a round cake pan that is 2 inches deep and has a 7-inch diameter
2. a 6 inch × 9-inch rectangular cake pan that is 2 inches deep
Which of these pans has the larger volume? Justify your answer.

Note: Write an essay-like answer, and I will give brainliest and rating.

Answers

The answer is

round cake - 82.42 in²

rectangular cake - 114 in²

Round cake:

d = 7 in

r = d/2 = 7 in / 2 = 3.5 in

h = 2 in

The surface are of a cylinder is:

A = 2πr² + 2πrh

The surface are of the round cake (which is actually a cylindrical cake) excluding the bottom is:

A = 2πr² + 2πrh - πr²

A = πr² + 2πrh

A = 3.14 * 3.5² + 2 * 3.14 * 3.5 * 2

= 38.46 + 43.96

= 82.42 in²

Rectangular cake:

w = 6 in

l = 9 in

h = 2 in

The surface are of a rectangle is:

A = 2wl + 2wh + 2lh

The surface are of the rectangular cake excluding the bottom is:

A = 2wl + 2wh + 2lh - wl

A = wl + 2wh + 2lh

A = 6 * 9 + 2 * 6 * 2 + 2 * 9 * 2

= 54 + 24 + 36

= 114 in²
