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.

If RST RS 15 RT 12 and ST 17. Which angle of RST has the smallest measure?
The angle opposite side RT = 12 will have the smallest measure
What is the measure of an interior angle of a normal polygon with 15 sides?
Each interior angle will measure 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??
How do you figure out angle measure of percent?
add 15 to it
