find the size of x and y
this is a figure of parallelogram

Answers

Answer:

x = 75° , y = 105°

Step-by-step explanation:

Opposite angles in a parallelogram are equal , then

x = 75°

Consecutive angles in a parallelogram are supplementary, sum to 180° , so

x + y = 180° , that is

75° + y = 180° ( subtract 75° from both sides )

y = 105°

The constructions that are crucial to draw a circle inscribed on the given equilateral triangle are:

Construct line segmentsConstruct angle bisectors.

How to make an inscribed circle in a triangle?

There can be many different ways, one can include arc way, one can include angle bisector and perpendicular, and we can even try to discover some. But usually, (for the angle bisector and perpendiculars), we do the following:

Divide one of the angles in half.Divide another angle in half.The incenter, or point where they cross, is the inscribed circle's centre.Construct a perpendicular from the triangle's centre point to one of its sides.Draw an inscribed circle by placing the compass on the centre point and adjusting the length to where the perpendicular crosses the triangle.

Drawing random arcs isn't gonna help mostly neither unspecific line segments. Drawing angle bisectors of the triangle and perpendiculars is one of the part.

Thus, the constructions that are crucial to draw a circle inscribed on the given equilateral triangle are:

Construct line segmentsConstruct angle bisectors.

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b percent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

data limit. Solve the inequality and show all of your work.

Answers

Answer:

[tex].75M+3<15[/tex]

[tex]M<16[/tex]

Step-by-step explanation:

This is a linear inequality so you would solve it as any normal linear system:

Subtract 3 from both sides to isolate the M term :

[tex].75M<12\\[/tex]

Divide each side by .75 to isolate M:

[tex]M<16[/tex]

That means you can watch less than 16 movies and stay under your 15GB limit.

In rectangle QRST, QS = 5x - 31 and RT = 2x + 11.
Find the lengths of the diagonals of QRST.

A.4
B.6
C.14
D.16

Answers

Answer:

Step-by-step explanation:

The diagonals of a rectangle are congruent, then

5x - 31 = 2x + 11 ( subtract 2x from both sides )

3x - 31 = 11 ( add 31 to both sides )

3x = 42 ( divide both sides by 3 )

x = 14

Then

RT = 2x + 11 = 2(14) + 11 = 28 + 11 = 39

The diagonals are each 39 units

Answer:

H = .298

Step-by-step explanation:

First lets plug in 1.5 for R and 16 for Surface area to get the following

2*pi*1.5^2+2*pi*h = 16 We are solving for H or height

Lets simplify this out a bit to get

16 = 14.13+6.28h

Subtract 14.13 from both sides

1.87 = 6.28h

h= .298

To check our answer lets plug the height into the equation

2*pi*1.5^2+2*pi*.298 = 16

Yes the height or H is .298

To check your answer just plug back what you got before into the equation
