Answer 1

Answer:

X=12.75

Y=12

Step-by-step explanation:

4X+8°+31°=90°

4X=90-39/4°

X=12.75°

3Y+86=8Y+26

86-26=8Y-3Y

60=5Y

Y=60/5

Y=12

Answer 2

Answer:

x = 12.75

y = 12

Step-by-step explanation:

To solve for x, we can see that it makes up a right angle when placed next to the 31 degrees.

We also know that the corner should equal 90 degrees, so we can set this up:

4x+8+31=90

Group like terms:

4x=51

Divide:

x=12.75

To solve for y, we can see that two expressions equal the same length, so:

8y+26=3y+86

Group like terms:

5y=60

y=12

You can also plug in x and y in to see if they match up

4(12.75)+8+31=90

51+8+31=90

90=90

and

8(12)+26=3(12)+86

96+26=36+86

122=122

Answers

Answer:

20 yards squared.

Step-by-step explanation:

First, you should convert your units. Three feet make a yard, so 15 feet = 5 yards and 12 feet = 4 yards.

The area of a square is found by multiplying the length and width, so 5 yards x 4 yards = 20 yards.

Each side of a square patio is 10.5 feet. The patio is made up of 1.5 foot by 1.5-foot square stones. What is the number of stones in the patio? Look at the solution below.
Does it include all the steps needed to solve the problem? Explain

10.5 x 10.5 = 110.25 PLZ SOLVE THE PROBLEM
110.25 ÷ 1.5 = 73.5

Answers

The steps your teacher gave you are on the right track, but not quite 100% correct.

The first line has us find the area of the entire patio. That area being 110.25 square feet.

The next step is to find the area of each stone. That would be 1.5 x 1.5 = 2.25 square feet.

Therefore, the patio is made up of 110.25 ÷ 2.25 = 49 tiles

When arranged into a square, we'll have a 7 by 7 square set of stone tiles. Notice how 7 x 7 = 49.

angle 1 and angle 2 form a linear pair. if m angle 1= x + 47, and m angle 2 = x-12 find the measure of angle 1

Answers

Answer:

215/2

Step-by-step explanation:

A linear pair means that the angles equal 180 degrees.

If added together 1 and 2 equal to 180 degrees, then the equation should be x+47+x-12=180. Then solve and simplify.

x+47+x-12=180

2x-35=180

2x=215

x=215/2

What is the length of DE
A. 18
B. 12
C. 10
D. 22

Answers

Answer:

the length of DE is A) 18

Step-by-step explanation:

these triangles are similar so you need to create a proportion!

since sides DF and FE are the same, it means that AC and CB are the same!

now we have to find the hypotenuse for DE, which is X

- set up a proportion!

side AC/side AB = side DF/side DE ----> 15/27 = 10/x

- butterfly multiply to get 15x = 270

- divide both sides by 15 to isolate x

now you get --------> x = 18!

Determine the measure of the indicated
exterior angle in the diagram.

Answers

Answer: 110 degrees

Triangle sum theory tells us that all the internal angles are equal to 180.

Meaning, we can solve 2x+3x+3x+4=180 for x

x=22

Then solve for 3x+4, which equals 70.

Last step, take 70 from 180 to find the external angle!

110 :)

Answer:

Exterior angle is equal to 110

Step-by-step explanation:

So to find the exterior angle, you must find the interior angle first.

You know that all 3 angles within the triangle must equal to 180 degrees, so what we can do is set up this equation to reflect that statement:

2x+3x+(3x+4) = 180

Group like terms:

8x+4=180

Solve for x:

8x = 176

x = 22

We can double check to see this matches up with all of the other angles inside:

2x = 44

3x = 66

3x+4 = 70

44 + 66 + 70 = 180

We also know that a straight line is 180 degrees

So, ? = 180 - 70

? = 110 degrees

Answers

Answer:

1,056

Step-by-step explanation:

16 x 6 = 96

96 x 11 = 1,056

Hey there!

16 * 6 * 11

16 * 6

= 16 + 16 + 16 + 16 + 16 + 16

= 32 + 32 + 32

= 64 + 32

= 96

= 96 * 11

= 96 * 11

= 96 + 96 + 96 + 96 + 96 + 96 + 96 + 96 + 96 + 96 + 96

= 192 + 192 + 192 + 192 + 192 + 96

= 384 + 384 + 288

= 768 + 288

= 1,056

Therefore, your answer is: 1,056
