Answer:
Length: 16.7
Perimeter: 41.2
Step-by-step explanation:
65.13 divided by 3.9 = 16.7 which is the length. You can use this expression: (16.7 x 2) + (3.9 x 2) to get a perimeter of 41.2.
Answer:
8
Step-by-step explanation:
All the angles in a circle equal to 360 degrees. So basically just add up all the known values: 23+23+15=61 and then subtract that from 360: 360-61=299.
You can also do 23+23+15+x=360. Adding it all becomes 61+x=360, subtract 61 from both sides of the equation, and you get x=299.
(Something to help remember is that the angle is obtuse, meaning it’s automatically more than 90 degrees, hope this helps!)
