So, here we have a hexagon. In geometry, there is a rule which says that the sum of all the angles inside a hexagon is equal to 720 degrees.
So, all we have to do is figure out the sum of the 5 angles we already have, and subtract that from 720.

112+133+128+100+120=593 (if I calculated that correctly)

So our angle ‘x’ would be 720-593, or 127 degrees.

Which equation represents a line that is perpendicular to line l on the graph below?

Bad White [126]

Answer:

y= -1/2x + 3

Step-by-step explanation:

A line perpendicular will have the reciprocal slope.

First you need to find the slope of the line given.

m= rise/ run

m= -2

Now flip for the reciprocal.

The perpendicular line will have a slope of -1/2

Solve the triangle.

saw5 [17]

Answer:

Step-by-step explanation:

because <u>c</u> is shorter than<u> a</u> we know C is a smaller angle than A

so the first choice is out.

use the law of cosines to find b

$b^{2}$ = $a^{2} +c^{2} -2*a*c*cos(B)$

$b^{2}$ =1681+400-1326.787871

$b^{2}$ = 754.21219

b= $\sqrt{754.21219}$

b= 27.46292

so the last choice looks good
