Answer:

x=10, y=20

Step-by-step explanation:

okay so to find x, or the way I did it, we just have to look at the top, we know one line is 180 degrees, and we see three angles, 7x,90, and 20

so 90+20+7x=180

and:110+7x=180

therefore: 7x=70

and finally: x=10

To find y also isn't had if we just look at the blue and green lines we see they are intersecting and opposite angles in intersecting lines are congruent meaning they are the same. So we now know that:

5x+2y=90

and we know x=10

so 5x=50

meaning that: 50+2y=90

therefore: 2y=40

and in conclusion y=20

Answer:

Step-by-step explanation:

The diameter is 2πr or 4032π in this. The arc from B to C counterclockwise is 130° out of 360°. 130/360 multiplied by 4032 is 1456

Angle 1 and 2 are supplementary. Angle 1=3x° angle 2=(2x. -25)° select from the drop down menu

goldfiish [28.3K]

Answer:

x = 41°

∠1 = 123°

∠2 = 57°

Step-by-step explanation:

If angles 1 & 2 are supplementary, that means...

$\angle1 +\angle2=180\textdegree$

To find the value of each angle, you first must find the value of x by plugging in the values of both angles...

$\angle1 +\angle2=180\textdegree\Longrightarrow3x+(2x - 25) = 180\textdegree$

First, combine like values, then subtract add 25 to both sides.

$3x + 2x = 5x\Longrightarrow 5x - 25+ (25) = 180 + (25)\\\\5x=205$

Then, divide both sides by 5, and plug the value of x into the original equations for angles 1 & 2.

$\frac{5x = 205}{5}\\\\x = 41\textdegree\\\\\angle1= 3x = 3(41) = 123\textdegree\\\\\angle2=2x-25=2(41)-25=82-25=57\textdegree$

Since the area of the poster doesn't change by putting it in a frame, we presume the question is asking what the area of the framed poster is.

The length of the poster in its frame is ...
(frame width on one side) + (poster length) + (frame width on the other side)
2 in + 32 in + 2 in = 36 in

Likewise, the width of the poster in its frame is ...
2 in + 24 in + 2 in = 28 in

The area of a rectangle 36 in by 28 in is the product of these dimensions:
Area = (36 in)×(28 in) = (36×28) in² = 1008 in²

Yuri [45]

Answer:

first method

22=5

7. x

we cross multiply to get

22x= 5×7

22. 22.

x= 35

=1.59

second method

22=5

7. x

we multiply the denominators to get 7x

then we multiply each term by 7x

7x×22 = 5×7x

7. x

here the 7 and 7 will cancel out and the x and x will cancel out to get

22x= 35

22. 22

= 1.59

Answer:

-7/48

Step-by-step explanation:

Put the numbers in place of the corresponding variables and do the arithmetic.

$\dfrac{-\left|1\dfrac{7}{8}+(-1)\right|}{2-(-4)}=\dfrac{-\dfrac{7}{8}}{6}=-\dfrac{7}{8\cdot6}=\boxed{-\dfrac{7}{48}}$
