Answer:

Step-by-step explanation:

The central angle <HEG = 88 degrees as well -- same as the arc you were given.

<HFG = 44 degrees because the angle sits on the circumference opposite the central angle.

That means that

8x - 40 = 44 Add 40 to both sides

8x = 44+40 Combine

8x = 84 Divide by 8

8x/8 = 84/8

x = 10.5

How do you do 51 and 54?

NemiM [27]

51. I checked the comments but I still didn't understand it, sorry :/

54.

(43+45+47+49)=184

They are all odd and they are in consecutive order (one after another)

Angle 1 is vertical to Angle 2. Angle 1 =94, Angle 2 = 2(x-13), Find the value of x.

rodikova [14]

Answer:

x= 56

Step-by-step explanation:

86+94= 180 which if supplementary angles have to equal 180°

I don't know if you can tell but what's in red means distribute

then I added 26 on both sides with like terms

on the left side 86+26=112 and right side is left with 2x

then divide both sides by 2 to leave x by itself

112/2= 56 and 2x/2=x

so 56=x
