Step-by-step explanation:

I don't know if this is the right way to so it, but I would do it like this

since a triangle has 180 degrees, the angles all have to add up to 180

So 180 = a + b + c

we already know a, its 95

So 180 = 95 + b + c

now we know the equation for b, so we'll just put it there instead of the b, and since the angles are the same, we should put it instead of c too

180 = 95 + (4x-15) + (4x-15)

now subtract 95 from both sides

85 = (4x-15) + (4x-15)

add the xs and numbers together

85 = 8x - 30

now add the 30 to both sides

115 = 8x

divide by 8

your x is 14 3/8 or 14.375 or 115/8

that's not your angle, that's your x

A circle has a circumference of 37 millimeters. What is the circle's

olasank [31]

Answer:

5.9

Step-by-step explanation:

To find radius from circumference you need to divide it by pie. So 37 divided by 3.14 is 11.7834394904. This is the diameter. Now divide it by 2, in this case it is 5.89171974522. When you round to the nearest tenth it gives you 5.9. Hope this Helps!

BEG is a triangle. ABC and DEF are parallel lines. work out the size of angle x.

worty [1.4K]

Answer:

$x=60^o$

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the measure of angle BEG

we know that

$m\angle BED+m\angle BEG+m\angle GEF=180^o$ ----> by supplementary angles (form a linear pair)

substitute the given values

$110^o+m\angle BEG+25^o=180^o$

$m\angle BEG=180^o-135^o=45^o$

step 2

Find the measure of angle HBC

we know that

$m\angle HBC+m\angle ABH=180^o$ ---> by supplementary angles (form a linear pair)

we know that

$m\angle ABH=110^o$ ---> by corresponding angles

substitute

$m\angle HBC+110^0=180^o$

$m\angle HBC=180^o-110^o=70^o$

step 3

Find the measure of angle EBG

we know that

$m\angle EBG+m\angle GBC+m\ angle HBC=180^o$

substitute the given values

$m\angle EBG+35^o+70^o=180^o$

$m\angle EBG=180^o-105^o=75^o$

step 4

Find the measure of angle x

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle BEG

$m\angle BEG+m\angle BGE+m\angle EBG=180^o$

substitute the given values

$45^o+x+75^o=180^o$

$x=180^o-120^o=60^o$

What is the solution to the equation 4(2-x)=5x-17

Travka [436]

Answer:

x = 25/9 or 2.777777778

Step-by-step explanation:

4(2-x) = 5x - 17

8 - 4x = 5x - 17

<u> +4x +4x</u>

8 = 9x - 17

<u>+17 +17</u>

25 = 9x

25/9 = x

x = 2.777777778 or 25/9
