Answer:

Step-by-step explanation:

x , u are parallel lines and v is transversal.

∠1   = ∠b     {Corresponding angles}

∠2 = ∠a   {corresponding angles}

∠1 +∠a = 180   {linear pair}

∠2 +∠ b = 180  {linear pair}

∠a +∠b  = 180   {co interior angles}

Answer:

1=b. 2=a

Step-by-step explanation:

Since there are corresponding angles, 1 and b will be congruent, and 2 and a will be congruent.

The vertices of triangle PQR are given in the standard (x,y) coordinate plane below. What is the area, in the square coordinate
alekssr [168]

Answer:

Area = 12

Step-by-step explanation:

Given

See attachment

Required

Area of \triangle PQR

From the attached image, we have:

P = (6,10)

Q = (10,8)

R = (6,4)

The area is then calculated as:

A = \frac{1}{2}|(x1y2 - x2y1) + (x2y3 - x3y2) + (x3y1 - x1y3)|

So, we have:

A = \frac{1}{2}|(6*8 - 10*10) + (10*4 - 6*8) + (6*10 - 6*4)|

Using a calculator:

A = \frac{1}{2}|-24|

Remove absolute bracket

A = \frac{1}{2} * 24

A = 12

It takes 10 minutes to fill a 60-gallon bathing pool. What is the average rate in gallons per hour
Lerok [7]
3,600 gallons per hour because there is 60 minutes in an hour and you started with 10 minutes so you multiply 60 by 60.

Hello, please help me answer these questions. Thanks

Answer:

1. C = 360 - (77 + 123 + 86) = 74

2. x = 252

   D = 290

3. x = 20

  S = 47

  P = 131

4. 36, 72, 108, 144

Step-by-step explanation:

Quadrilaterals are composed of two triangles. Seeing as we know the sum of the interior angles of a triangle is 180°, it follows that the sum of the interior angles of a quadrilateral is 360°.

1. C = 360 - (77 + 123 + 86) = 74

2. x + 38 = 360 - (124 + 97 + 69) = 290

   x = 290 - 38 = 252

   D = 290

3. (27 + x) + (3x + 71) = 360 - (119 + 63)

   27 + x + 3x + 71 = 178

  4x = 80

  x = 20

  S = 27 + x = 27 + 20 = 47

  P = 3x + 71 = 3(20) + 71 = 131

4. Let angles be x, 2x, 3x, 4x then

   x + 2x + 3x + 4x = 360

   10x = 360

   x = 36

  then the angles are 36, 72, 108, 144
