Well recalling that the formula for the sum of the interior angles is 180(n-2) where n is the number of sides, add all of the values of the variable up and set it equal to your sum value

#

Then plug back in the solution for your variable to the angles you are looking for

#

So add everything up and then plug into the formula ?

#

So how many sides are there in a pentagon?

#

Ok

sturdy sundial Apr 4, 2024, 1:46 AM

#

Oh (5-2)180

delicate flicker Apr 4, 2024, 1:46 AM

#

Yes

#

Then add the inside values like 9n.. 10n etc up

#

And set it equal to solve for n

sturdy sundial Apr 4, 2024, 1:46 AM

#

45

#

And plug it back in to get the specific angles

#

Ok

#

45n = 540

#

Solve for n then plug it back into the expressions for angle P and angle Q
