Can someone help me with this please

OpenStudy (anonymous):

How would I solve this

OpenStudy (anonymous):

is this for your summer school?

OpenStudy (anonymous):

yes :(

OpenStudy (anonymous):

it's pretty hard

OpenStudy (anonymous):

which grade are you in

OpenStudy (anonymous):

yeah I'm having a hard time on some of them

OpenStudy (anonymous):

I'm in 11th

OpenStudy (anonymous):

@satellite73

OpenStudy (anonymous):

do you have any others?

OpenStudy (anonymous):

As of right now no I'm stuck on that one

OpenStudy (anonymous):

are you good in math normally

OpenStudy (anonymous):

no I've always struggled :l

OpenStudy (anonymous):

we can break this down. Lemme draw a diagram

OpenStudy (anonymous):

ok thank you :)

OpenStudy (anonymous):

well no need for diagram. Whenever you inscribe a quadrilateral within a circle, remember that opposites angle of the quadrilateral adds up to 180 so, x-15 + 91 = 180 solve for x. Quadrilateral can be anything that has 4 sides, including rectangle square rhombus parallelogram, weird funky things with 4 sides etc.

OpenStudy (anonymous):

There's a way to prove that but in this case not necessary :)

OpenStudy (anonymous):

so would it be 106?

OpenStudy (anonymous):

or would i subtract the number i got to get 74

OpenStudy (anonymous):

106? x= 180-91+15

OpenStudy (anonymous):

ok got it

OpenStudy (anonymous):

thank u for helping me
