Answer: ∠DOB: 48°
Step-by-step explanation:
1. we need an equation first. the sum of all angles (108°, n°, 2n°) is equal to 180°. we can depict this with the equation: 108°+2n°+n°=180°
2. now we can solve for the missing variable, n.
108°+3n°=180° → subtract both sides by → 3n°=72° → divide both sides by 3 → n=24°
3. now that we know that n=24°, we can solve the value of ∠DOB. we can see that ∠DOB is 2n° which we just plug the number we got for n into the equation. 2*24=48° meaning ∠DOB is 48°
hope this heped! ♡
Answer:
Step-by-step explanation:
- We first compute the ratio of this geometric sequence.
- We simplify the fractions:
- We deduce that it is the common ratio because it is the same between each pair.
- We use the first term and the common ratio to describe the equation:

Answer:3
Step-by-step explanation:
Answer:
4320 degrees
Step-by-step explanation:
If interior angles are 3960 degrees then there are 24 sides. If polygon is regular, size of each exterior angle is 15 degrees.
A polygon has as many pairs of interior and exterior as number of its sides. Further each pair of exterior and interior add up to
180 degrees.
Sum of all the exterior angles of any polygon is
360 degrees
As sum of all the interior angles of the polygon is
3960 degrees
Sum of all pairs of exterior and interior angles is
3960 degrees + 360degrees = 4320 degrees
