C b/c 180° - 44° = 136°. Angles DEB & AED add up to 180° b/c they are supplementary angles.

Given m||n, find the value of x
ICE Princess25 [194]

By using the corresponding angles theorem we can see that (6x - 5)° and (x - 25)° are supplementary angles, so they add up to 180°.

This means that:

(6x - 5) + (x - 25) = 180

7x - 30 = 180

7x = 210

x = 30

If you want to find the exact values of the angles, just plug x = 30 into the angle values! :)

1.2million users of social media via mobile devices were added each day. How many users added on an average each second
Pachacha [2.7K]

Answer: 14 new users are added per second

Step-by-step explanation:

1,200,000/24 = 50000

50000/60 = 833.333333333

833.333333333/60 = 13.8888888889

then round because it said on average

so if we round 13.8888888889 we get 14

so on average 14 new users are added per second.

Two line segments intersect as shown.
kolbaska11 [484]

Answer:

CE congruent ED

Step-by-step explanation:

A perpendicular bisector is a line segment which perpendicularly intersects another line, thereby dividing it into two equal parts. In fact, the Perpendicular bisector theorem states that if a point is on the perpendicular bisector of a segment, then it is equidistant from the segment’s endpoints.

  • The perpendicular bisector, AB, bisects CD at a point E, that is, the length CE is equal to ED. And the angle formed between the two lines is 90 degrees.

Therefore, the additional pertinent information that allows for the conclusion that AB is a perpendicular bisector of CD is that "CE congruent ED".

What is the simplified form of 3/4x+3+21/8x^2-14x-15
creativ13 [48]

Solution:

We have been asked to find the simplified expression of

3/4x+3+21/8x^2-14x-15=\frac{3}{4x+3} +\frac{21}{8x^2-14x-15}\\ \\ \text{We will have to make the denominator equal to add}\\ \\ \ 8x^2-14x-15=8x^2+6x-20x-15\\ \\ \ =2x(4x+3)-5(4x+3)=(4x+3)(2x-5)\\ \\  \frac{3}{4x+3} +\frac{21}{8x^2-14x-15}=\frac{3}{4x+3} +\frac{21}{(4x+3)(2x-5)}\\ \\ =\frac{3(2x-5)+21}{(4x+3)(2x-5)}\\ \\ =\frac{6x-15+21}{(4x+3)(2x-5)} \\ \\ =\frac{6x+6}{(4x+3)(2x-5)} \\

Find the surface area of this cylinder round to the nearest tenth
lozanna [386]

Step-by-step explanation:

The surface area of a cylinder is given by

A = 2\pi r^2 + 2\pi rL

\:\:\:\:=2\pi(3\:\text{cm})^2 + 2\pi(3\:\text{cm})(12\:\text{cm})

\:\:\:\:= 282.7\:\text{cm}^2
