1. a = 1/2x - 3
2. a = 2x + 7
Answer:
1/1
Step-by-step explanation:
22/22 =1
To find the measure of an interior angle of any regular polygon, we use the formula:
180 * (n-2) / n,
where n is the number of sides in the regular polygon.
Therefore, if there are 15 sides in the regular polygon, your answer would be
180 * (15-2) / 15,
or when simplified,
180 * 13 / 15
2340 / 15
156 degrees.
Thus, the measure of an interior angle of a regular polygon with 15 sides is 156 degrees.
Answer:
∠XVW = 36°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠WXY is an external angle to the triangle and
∠XVW and ∠VWX are the 2 opposite interior angles, thus
6x - 19 = x + 17 + 3x + 2, that is
6x - 19 = 4x + 19 ( subtract 4x from both sides )
2x - 19 = 19 ( add 19 to both sides )
2x = 38 ( divide both sides by 2 )
x = 19
Hence
∠XVW = x + 17 = 19 + 17 = 36°
