Answer:
<em><u>9</u></em>
Step-by-step explanation:
= x + 16° + x + 3° =5x - 8°[ Sum of two interior angles is equal to the exterior angle]
or, 2x + 19 = 5x - 8
or, 19 + 8 = 5x - 2x
or, 27 = 3x
or, x = 27/3
☆ x= 9

Answer: Apothem
Step-by-step explanation: Half of an octagon is called an apothem
2.9*10^10+ 5.35*10^10
= (2.9+ 5.35)*10^10 (distributive property)
= 8.25*10^10
The correct answer is A. <span>8.25 times 10^10~</span>
Answer:
b. (x + 16)° + (6x − 4)° = 180°
Step-by-step explanation:
As we know that in a quadilateral the total of the opposite angles in a circle is equivalent to the 180 degrees
As seen in the attached figure
∠ROP + ∠RQP = 180 degrees
So
(x + 16)° + (6x - 4)° = 180 degrees
Hence, the correct option is b.
Therefore all the other options which are given is incorrect
