Answer: 16.
Step-by-step explanation:
All angles in any pentagon add up to 540 degrees.
As such, you can represent each angle in an equation in which the sum of all the angles is 540, as follows:

They do not have the same value because 17 times 10 is 170 because all u need to do is add a zero at the end
Number 1 is 4 4/5#2 is-3 #3 is > anf # 4 is 13 units
Answer:
Given: Point C is the center of circle.
To Find: ∠ A CB
Solution: Measure of arc A DB=312°
Angle made by complete circle=360°
⇒∠A DB + ∠ AC B= 360°[Total measure of complete circle]
⇒ 312° + ∠ AC B= 360°
⇒∠ AC B = 360° - 312°
⇒ ∠ AC B=48°
