Answer:

G = 50

H = 80

I = 50

Step-by-step explanation:

Angle in a triangle is equal to 180. This means that we will equal all the angles to 180

2x + 2x + 4x-20 = 180

8x - 20 = 180

8x = 180 + 20

8x = 200

x = 200 / 8

x = 25

G = 2 * 25 = 50

I = 2 * 25 = 50

H = 4 * 25 - 20

H = 100 - 20 = 80

Percy drew a scale drawing of a hotel. A room in the hotel is 6 inches long in the drawing. The actual room is 24 feet long. What scale did Percy use for the drawing?

Answers

Answer: 1 inch : 4 feet

Step-by-step explanation:

Given: A room in the hotel is 6 inches long in the drawing.

The actual room is 24 feet long.

i.e. 6 inches in the drawing = 24 feet (in actual)

1 inch in drawing = [tex]\dfrac{24}{6}[/tex] feet

i.e. 1 inch in drawing = 4 feet

The scale of drawing Percy used for the drawing:

1 inch : 4 feet

The lines p and q intersect at point O. What is the value of x? Enter your answer in the box. x = Lines p and q intersect at point O. Acute vertical angles measure two x plus thirteen degrees, and three x minus three degrees.

Answers

Answer:

x = 16

Step-by-step explanation

Find the diagram attached. You can see from the diagram that both angles are vertically opposite angles and vertically opposite angles are equal.

Hence 2x+13 = 3x-3

Collect like terms

2x-3x = -3-13

-x = -16

Multiply both sides by -1

-1(-x) = -1(-16)

x = 16

Hence the value of x is 16

Answer:

x=16 hope this helps!

Segment ME has a length of 13 inches and is rotated 270∘ counterclockwise about the origin to segment M′E′. What is the length of segment M′E′?

Answers

Answer: Should be 13

Step-by-step explanation:

The length of the segment M′E′ when segment ME is rotated 270∘ counterclockwise about the origin is 13 inches.

What is rotation of figure?

Rotation of a figure is the transformation of it about a point in either clockwise or anticlockwise direction. By rotating, a figure changes the point of the figure.

For example, let suppose a line segment has the end point (0,3) and (0,6). By rotating it from one of its end point (0,3) 90 degree clockwise will change its location.

The new location of the line will be (0,3) and (3,3) as it is rotated 90 degree clockwise. Here, the initial length of the line is 3 units. After the rotation, the length is still 3 units long.

So, it can be concluded that rotation of a figure does not change the length of it.

The rotation of a line segment does not change the length of it. Hence, the length of the segment M′E′ when segment ME is rotated 270∘ counterclockwise about the origin is 13 inches.

Anyone wanna help me out??

Answers

Answer:

6955 ft

Step-by-step explanation:

Refer to attached. Point J, segment BJ and angle measures added.

Step 1, find BJ

BJ / AB = sin 20° ⇒ BJ = AB sin 20° ⇒ BJ = 600 sin 20° ≈ 205.2 ft

Step 2, find BP

BJ/BP = cos 75° ⇒ BP = BJ / cos 75° ⇒ BP = 205.2/cos 75° ≈ 792.8 ft

Step 3, find PQ

PQ/BP = sin 35° ⇒ PQ = BP sin 35° ⇒ PQ = 792.8 sin 35° ≈ 454.7 ft

Step 4, find the elevation of peak P

Height above sea level = 6500 + 454.7 ≈ 6955 ft (rounded)

Just curious, I want to see who can get this. tooooootttalllllly know it alreadyAssume that we have two variables a and b, and that: a = bMultiply both sides by a to get: a2 = abSubtract b2 from both sides to get: a2 - b2 = ab - b2This is the tricky part: Factor the left side (using FOIL from algebra) to get (a + b)(a - b) and factor out b from the right side to get b(a - b). If you're not sure how FOIL or factoring works, don't worryyou can check that this all works by multiplying everything out to see that it matches. The end result is that our equation has become: (a + b)(a - b) = b(a - b)Since (a - b) appears on both sides, we can cancel it to get: a + b = bSince a = b (that's the assumption we started with), we can substitute b in for a to get: b + b = bCombining the two terms on the left gives us: 2b = bSince b appears on both sides, we can divide through by b to get: 2 = 1 Which of these BEST explains why most of Canada's population has settled near its border with the United States?
