Please help me. solve for X

Mathematics
1 answer:
Vinil7 [7]3 years ago
6 0

Answer:

1. x = 16

2. x = 17

Step-by-step explanation:

1. The sum of the exterior angles of any polygon is 360 degrees. So, to find x, we can add up all of the angle measures and set them equal to 360, then solve for x:

46 + 93 + 47 + 4x + 62 + 3x = 360

Combine like terms:

248 + 7x = 360

Subtract 248 from both sides of the equation to isolate 7x:

7x = 112

Divide both sides by 7 to find the value of x:

x = 16

2. The sum of the interior angles for a 5-sided polygon is 540 degrees. So, to find x, we can add up all of the angle measures and set them equal to 540, and then solve for x:

5x + 139 + 9x + 71 + 92 = 540

Combine like terms:

14x + 302 = 540

Subtract 302 from both sides to isolate the 14x:

14x = 238

Divide both sides by 14 to find the value of x:

x = 17

I hope this helps :)

Hello I need help! IM GIVING BRAINLIEST, FIVE STARS AND THANKS to best answer :)
Natalka [10]

Answer:

1. 4 hours and 10 minutes

2. 8:40 to 12:00

4. 6 hours and 50 minutes

5. 2:25 pm

6. 9:15 am to 12:35pm

7. 3:00pm

(second) 7. 2 hours and 45 minutes

Step-by-step explanation:

1. 2+4 = 6 so then after add 10 to the 45

4 hours and 10 mins

-

2. 8+3= 11 so its 11:40 right now, add the other 20 minutes, you end up with 12:00.

-

4.It's better off to start with 12 so add 3 hours and 30 minutes to get to 12:00pm. Now to 3:20pm would obviously be 3 hours and 20 minutes.

3 hours + 3 hours = 6 hours. 30 minutes + 20 mins = 50 mins. 6 hours and 50 minutes.

-

5. 10:15 + 4 hours would be 2:15 now add the 10 and that would be 2:25pm.

-

6. 9:15 a.m to 12:35pm would be right. The elapsed time is 5 hours and 20 minutes. 10:30 P.M to 1:15 A.M would be close but it's 5 minutes lesser. 11:10 pm to 2:15 am would be 3 hours and 5 minutes. 6:45pm to 10:00pm would be 3 hours and 15 minutes.

-

7. Making it simpler, add 15 minutes so that makes it 12:00pm. Then just add the 3 hours. 3:00P.M.

3:00 pm is your answer.

-

(second) 7. 10:30 pm to 1:15am. Also making it simpler, add 1 hour and 30 minutes. Now just add 1 hour and 15 minutes. Add both times,

1 hour and 30 minutes + 1 hour and 15 minutes = 2 hours and 45 minutes.

Find the product of the monomial and polynomial xyz*(2x+3y^2-3z^2)
marissa [1.9K]

Answer:

2x^2yz + 3xy^3z - 3xyz^3

Step-by-step explanation:

First you must distribute:

xyz(2x) + xyz(3y^2) + xyz(-3z^2)

Then simplify:

2xyxx + 3xyzy^2 - 3xyz * z^2

And finally simplify each term:

2x^2yz + 3xy^3z - 3xyz^3

Molly needs to classify the triangle below based on angles. Which class is correct? 60° 50° 70° A. acute triangle О B. isosceles
Art [367]

Answer:

A. Actute triangle

Step-by-step explanation:

Is A because an acute triangle is a triangle where all the angles are the same.

Can not be B. because isosceles triangles have two sides that are the same which doesn't relate to angles.

Can not be C. because equilatiral triangles are triangles with sides that are all the same.

Can not be D. because for a triangle to be obtuse one of the angles needs to be greater that 90 degrees.

So it has to be A.

Which points are reflections of each other across both the y-axis
ser-zykov [4K]

Answer:

Reflect over the y-axis

Step-by-step explanation:

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed).

Notice that B is 5 horizontal units to the right of the y-axis, and B' is 5 horizontal units to the left of the y-axis.

The reflection of the point (x,y) across

the y-axis is the point (-x,y).
