A 15 sided shape's total number of degrees can be found using the formula (x-2)*180, where x is the number of sides.
Using this we find that a 15 sided shape's total degrees is 2340.
Divide that number by 15 to get the degrees of each interior angle.
It comes out to be 156 degrees.

In triangle ABC the measure of angle A is four times that of angle B In addition the measure of angle C is 15 degrees than half the measure of angle A?
This doesn't ask any question but I assume you want to know the measures of angles ABC.Well if C is 15 degrees LESS than half of angle A then the algebraic equation would look something like this:Let x = measure of angle B then 4x = measure of angle A, since angle A is four times angle Bthen 2x (half the measure of angle A = 4/2) - 15 = measure of C.Basic Knowledge:angle A+ angle B+ angle C=180°180 degrees = total measure of angles in a triangle4x° + x° + (2x - 15)° = 180°SOLVE for X!STEP 1: always combine (add/subtract) like terms7x°-15+15=180°+15(isolate the variable by adding 15 on both sides of the equation)_________7x°/7+0 = 195°/7 (solve for x by dividing 7 on both sides of the equation)_________x ≃ 27.86° or = (27 6/7)° = measure of angle B4x ≃ 111.44° = measure of angle A2x-15 ≃ 55.72°-15 ≃ 40.72° = measure of angle C**add them all up together, they would add up to 180.02° because x actually equals 27.857142857142857142.....Now if C is 15 degrees MORE than half of angle A then the algebraic equation would look something like this:again; Let x° = measure of angle Bthen 4x° = measure of angle A, since angle A is four times angle Bthen 2x (half the measure of angle A = 4/2) +15 = measure of C.4x° + x° + (2x + 15)° = 180°SOLVE for X! (same steps, just watch for the signs)7x°+15-15=180° -15 (subtracted 15 on both sides)_________7x°/7 +0 = 165°/7 (divided 7 on both sides)_________x ≃ 23.57° or = (23 4/7)° = measure of angle B4x ≃ 94.28° = measure of angle A2x+15 ≃ 47.14° +15 ≃ 62.14° = measure of angle C**add them all up together, they would add up to 179.99° because x actually equals 23.571428571428571428.....See the pattern?? and the difference??

What measure of angle A will make angle ABC congruent to angle FDE?
To have a congruent angle, the measure of the two angle must be the same, so if ABC is 15 degrees, then FDE would have to be 15 degrees also to be congruent.
What is the measure of an interior angle of a normal polygon with 15 sides?
Each interior angle will measure 156 degrees
The measure of the second angle of a triangle is 21 degrees more then the measure of the first angle the measure of the third angle is 15 degrees less than the measure of the first angle. each is?
Let the measure of the first angle be x⁰. So that the second angle would be (x + 21)⁰, and the third one would be (x - 15)⁰.Since the sum of angle measures in a triangle is 180⁰ we have:x + x + 21 + x - 15 = 1803x = 174x = 58Thus, the first angle is 58⁰, the second angle is 79⁰, and the third angle is 43⁰.
