72.32

Step-by-step explanation:

The line is 180 so

7x + 8x + 44.4 = 180

15x + 44.4 = 180

-44.4         =  -44.4

15x = 135.6

divide both by 15

x = 9.04

So 8 * 9.04 = 72.32

The answer is 72.32°

Step-by-step explanation:

So, since that is a straight line, we know that all of the angles add up to get 180° total. Using this knowledge, we can determine that 44.4 + 8x + 7x = 180°.

First, we need to find what x is to find the missing values. To do that, we have to set all the values, 44.4, 8x, and 7x equal to 180, because we know they add up to 180°.

44.4 + 8x + 7x = 180

Combine the like terms.

44.4 + 15x = 180

Bring the 44.4 over to the other side in order to get x alone by subtracting it from 180.

15x = 135.6

Divide both sides by 15 to get x completely alone.

x = 9.07

Now we have what x is, 9.07.

All you need to do now is substitute 9.07 into the place of x.

8(9.07) = 72.32

So now you know that the highlighted angle is 72.32°.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
