Answer:10+16b
Step-by-step explanation:10+6b+8
10+16b
You have to figure it out. First, the sum of the angles in a polygon = n-2(180) where n is the number of sides. For a pentagon, this is 5-2(180)=540. then divide by 5 for each of 5 large angles in the pentagon, and then divide by 2 for the angle formed by the radius in the right angle. This is 540/5=108 divided by 2 = 54 degrees in the right angle. Now that you know the angle , then use trig to solve the problem...

I feel bad for you I really would like to help you but I haven't even learn that stuff yet
Answer:
Hello! answer: x = 40
Step-by-step explanation:
These are vertical angles meaning they will have the same measure.
40 × 3 = 120 120 - 16 = 104 therefore x = 40 hope that helps!
