PLEASE HELP!!!!
grandymaker [24]
10 is 20 degrees

11 is 180-145= 35 degrees

12, so the way you do it is by the fact that one opposite exterior angle is equal to two interior angles, so 40+46= 86 degrees.

8 is 86-35= 51 degrees

9 is 29 plus 62 equals 91 degrees.

Hope this helps! I tried to type this really fast

Please find the angles
bulgar [2K]

Answer:

<1 = 50

<2 = 40

<3 = 90

<4 = 90

<5 = 40

<6 = 50

<7 = 130

Step-by-step explanation:

<5 + <6 = 90

40 + <6 = 90

<6 = 50

<5 = <2 because of vertical angles

<2 = 40

<6 = <1 because of vertical angles

<1 = 50

<7 = <4 + <5

<7 = 90 + 40

<7 = 130

How many is?<br> with procedure and testing<br> PLEASE<br><br> -4x + 13 = 6x - 7
slamgirl [31]
To solve for X you must get x by itself so let's get started
-4x+13=6x-7
subtract 13 from both sides
-4x=6x-20
subtract 6x from both sides
-10x=-20
divide both sides by -10
x=2

to check if this is correct plug in x into original equation
-4 (2)+13=6 (2)-7
-8+13=12-7
5=5
answer x=2 holds true :)
