Find the measure of x given interior angles of a pentagon

👉 Learn how to solve for an unknown variable in the interior angle of a polygon. A polygon is a plane shape bounded by a finite chain of straight lines. The interior angle of a polygon is the angle between two sides of the polygon. The sum of the interior angles of a regular polygon is given by the formula: 180(n - 2) degrees, where n is the number of sides of the polygon.

Given the expressions for the interior angles of a polygon, to find an unknown variable, we equate the sum of the expressions for the angles to the value of 180(n - 2) degrees, where n is the number of sides of the polygon and then solve for the unknown variable.

Thank you. Ive gained so much confidence since I’ve started using your You Tube videos for my math training.

[rowennazy]

You are impacting everyone man, please keep up.

[Jennifer-lwkk]

Your such a great teacher, I always watch your videos whne I don’t get a math problem

[Lucasman]

Hey! I'm studying for 7th grade accelerated midterms, and your videos keep popping up! They're so helpful! Thank you for making this content!

[Ohmigoshwppt]

Tysm my math quiz is literally in 10 minutes and this was the only thing I couldn’t figure out 🙏🙏🙏🙏

[ronkeomojola]

Even when I felt like giving up your channel always helps and God will bless you for that

[ignkayden]

Hey bro, keep up he good work you're such a dedicated teacher..

[saadid]

Omg thank you so much tmrw is my math test and I don’t know how to do this thank you 🙏🙏🙏

[themyst]

Wow... These questions are easier then I thought thank you!

[ravenlarios]

Thank you for your help to find the right answer

[evanbroaddus]

Helped me very much, you made it simple. Good vid!

[maxi_edits]

Thanks very much for this video, it helped me understand how to do this properly. 🎉

[taufiqahmad]

I didn’t understand my school teacher but I understand you thank you

[caedyn]

um.. so what if there was only one variable and the rest are whole numbers. Like 95 120 120 172 125 and then just an x? Do you just add them up and follow the rest you show us?

[entertainmentfeen]

I love how bro calls out his own students mid recording😭 0:57

[magnusthered]

Thanks I forgot how to solve for when I had a test today

[BeckyTaylor-ifex]

I don't know if there is a rule for writing the angles as (x+2), (x-8), (x+7), etc..I know these numbers add to zero - but they seem randomly assigned to the angles. Is there a rule that shows why he assigned those specific numbers to the angles?

[ericwells]

Can a four sided polygon have 3 inner angles of 91 degrees and one inner angle of 87 degrees?

[ljkoch]

how do you write it in general??? like if you didn't have the angle measures.

3 days later my exam is their and because of you I have confidence I won't fail
