Question

Find y if the left hand arc is 5y+ 5 degrees (image in comments)
a. 19
b. 0
c. 43
d. 7/3
e. none of the above

Answer 1

i know this by a different way.

Answer 2

could you walk me through your way again?

Answer 3

what is the angle of a straight line

Answer 4

180 degrees

Answer 5

no i have a straight line that is cut into two.
we will have 180 - (2y+12)

Answer 6

okay

Answer 7

Is that intersection of lines supposed to be ON the circle or INSIDE the circle? Ambiguous drawing.

Hint: Vertical Angles are Equal.

Answer 8

this will give me -2y+168 on the other side, correct?

Answer 9

correct

Answer 10

On the other side of what? You must FIRST actually WRITE DOWN an equation.

Answer 11

@tkhunny , then show how it is done please

Answer 12

yes please.

Answer 13

or not. alright continue @mickey4691

Answer 14

i will have (5y+5) + (-2y+18) which should give me 180

Answer 15

sorry it is 168 and not 18

Answer 16

okay

Answer 17

did you find the value of y?

Answer 18

7/3?

Answer 19

yes.

Answer 20

okay! i see what you did, thank you :)

Answer 21

i looked at in on a straight line way. there's plenty of ways to conduct that though

Answer 22

An inscribed angle is 1/2 the intercepted arc.

Unfortunately, it's not clear if we HAVE an inscribed angle.
Unfortunately, it's not clear if the angle measure indicated on the left is the angle itself or the intercepted arc.

Vertical angles are equal.

If it is the angle, itself, we have 5y+5 = 2y+12
If it is the intercepted arc, we have, ½(5y+5) = 2y+12
