Can someone help me with these problems

Answer:

i believe it is 231 yd squared

Step-by-step explanation:

Answer:

1. 231 yd²

2. 78 ft²

3. 28 inches

4. 57.5 centimeters

5. 258 cm²

Step-by-step explanation:

That is not geometry, but here are your answers.

A = bh

A = 13.2 × 17.5

A = 231 yd²

[tex]A=\frac{bh}{2}[/tex]

[tex]A=\frac{(13)(12)}{2}[/tex]

[tex]A=\frac{156}{2}[/tex]

A = 78

[tex]b=2\frac{A}{h}[/tex]

[tex]b=2\frac{364}{28}[/tex]

b = 28

[tex]h=2\frac{A}{a+b}[/tex]

[tex]h=2\frac{5405}{65+123}[/tex]

[tex]h=2\frac{5405}{188}[/tex]

[tex]h=2(28.75)[/tex]

h = 57.5

A = a²

A = 12²

A = 144 cm²

12 ÷ 2 = 6

[tex]A=\frac{(h)(b)}{2}[/tex]

[tex]A=\frac{114}{2}[/tex]

A = 57

57 cm² + 57 cm² = 114 cm²

114 cm² + 144 cm² = 258 cm²

Answer:

Each angle is 60°

Step-by-step explanation:

The 2 angles are equal to each other because they're alternate exterior angles:

10x - 20 = 7x + 4

10x - 7x = 4 + 20

3x = 24

x = 8

10x - 20

10(8) - 20

80 - 20

60

Since these angles are exterior angles, their angle measures are equal so they both are 60°

Answer:

h=square root of 55

area of triangle=15*square root of 5

Step-by-step explanation:

Answer:

a. 7.4 cm

b. 22.2 cm²

Step-by-step explanation:

a. Apply Pythagorean theorem to find h.

c² = a² + b²

Where,

c = 8 cm

a = 3 cm

b = h cm = ?

Plug in the values

8² = 3² + h²

64 = 9 + h²

64 - 9 = h²

55 = h²

h = √55

h ≈ 7.4 cm

b. Area of the triangle = ½*bh

b = 6 cm

h = 7.4 cm

Area = ½*6*7.4

Area = 22.2 cm²

Answer:

216 cm squared

Step-by-step explanation:

14*12 for rectangle area=168  because of l*w

for the triangle: 12 * 8 =96/2=48 because of A=1/2 * b*h

area equals 168+48=216 cm squared

Answer:

10157.08 m

Step-by-step explanation:

Find the area of the square, and get 10000, from multiplying 100 by 100. Then, find the circumference/area of the semi-circle as a whole circle. 314.16m. Divide it by 2 and get 157.08 m. Add everything up and get 10157.08 m. Remember, that we aren't calculating the total of both semi-circles because we subtract Figure A from Figure B.

[tex]7x + 21 = 5x + 3 \\ 7x - 5x = -21 + 3 \\ 2x = - 19 \\ x = - 19 \div 2 \\ x = - 9.5[/tex]

Answer:

Step-by-step explanation:

1) False

Adjacent angles must share a common side/ray.

2) B and D

Adjacent angles are those that are directly next to each other and share a common side.

3) C

Angles 1 and 2 are congruent. Angles 3 and 4 are congruent. Both of these pairs have angles that are opposite each other.

4) B

Angles 1 and 2 add up to 180. Angles 3 and 4 add up to 180. Both of these pairs of angles are supplementary.

5) A

These angles are directly next to each other and share a common side.

Hope this helps!! :)

Answers:

If an angle is labeled with a single letter, that letter represents the  vertex   of the angle.

If more than one angle has the same vertex, you must use  3   points to name the angle. The  middle   point named must be the vertex.

=================================================================

Explanation:

If we have a single triangle, and no other extra lines, then we can use single letters to name the three angles. Each vertex of the triangle corresponds to the vertex of that angle.

If you were to draw many triangles, in which some may or may not overlap, you'll mostly likely need to name the angle using 3 letters. This is so you are very specific about which angle you're talking about. The middle letter is always the vertex. The left and right letters are points on the arms of the angle. The order of the left and right letters doesn't matter as long as the middle letter stays the same. So something like angle ABC is the same as angle CBA.
