A five sided figure, the sum of all the angles must add up to 540 degrees.

In order to find x we are gonna add all the present angles and then minus the sum from 540 degrees.

76 + 144 + 112 + 125 = 457 degrees

540 - 457 = 83 degrees

Therefore x is equal to 83 degrees.

Sam had 1 1-2 m of rope. He cut off 5-8 m and used it for the project. How much does Sam have left

Answers

1 1/2 m and 5/8 meter need to have the same denominator in order to subtract.

1 1/2 is equivalent to 12/8
Now 5/8 and 12/8 have the same denominator so you can subtract.
12/8-5/8= 7/8
7/8 m is left

Find the equation of the straight line passing through the points (–2, 3) and parallel to y=2x-1

Answers

Answer:

[tex]y=2x+7[/tex]

Step-by-step explanation:

All parallel lines have the same slope, so in slope intercept form, our line is going to look like

[tex]y=2x+b[/tex]

To find b, we can plug in the x and y values from the given point (-2, 3) and solve:

[tex]3=2(-2)+b\\3=-4+b\\b=7[/tex]

So our equation becomes

[tex]y=2x+7[/tex]

Answer:

x = 43.5°

Step-by-step explanation:

The sum of the angles around a point = 360°

sum the angles and equate to 360

x + x + 72 + 111 + 90= 360

2x + 273° = 360° ( subtract 273° from both sides )

2x = 87° ( divide both sides by 2 )

x = 43.5°

Answer:

Sum of the angles around a given point is 360°.

[tex]x + x + 72 + 90 + 111 =360 \\ 2x + 273 = 360 \\2x = 360 - 273 \\ 2x = 87 \\ x = \frac{87}{2} \\ \boxed{x = 43.5°}✓[/tex]

★ x=43.5° is the right answer.
