Question

The measure of an obtuse angle is 5y+45. What are the restrictions on y? Pleasee Help?

Answer 1

An obtuse angle has to be GREATER than 90 degrees. So:
90=5y+45
Solve for y and you will have the lowest y value that will work!

Answer 2

Thanks i'll reply with my answer so you can check if its right

Answer 3

y=9 @Rhope

Answer 4

Also Obtuse < 180, so take that into account

Answer 5

The problem also requires an upper limit as well. So 180=5y+45.

Answer 6

Then put it in the form of an inequality: 9<y<180=5y+45.

Answer 7

@Rhope will that be the final answer?

Answer 8

No.

The final answer would be 9<y<18

Answer 9

ohhh i see makes sense thanks
