Answer:
A triangle similar to DEF will have an angle that measures 45 degrees, an angle that measures 65 degrees, and an angle that measures 70 degrees
Step-by-step explanation:
Given
See attachment for complete question
Required
Angles of a triangle similar to ![\triangle DE F](https://tex.z-dn.net/?f=%5Ctriangle%20DE%20F)
First, calculate the angle at D
---- angle on a straight line
Collect like terms
![D = 180^o - 110^o](https://tex.z-dn.net/?f=D%20%20%3D%20180%5Eo%20-%20110%5Eo)
![D = 70^o](https://tex.z-dn.net/?f=D%20%20%3D%2070%5Eo)
Next, calculate the angle at F
---- angle on a straight line
Collect like terms
![F = 180^o -135^o](https://tex.z-dn.net/?f=F%20%20%3D%20180%5Eo%20-135%5Eo)
![F = 45^o](https://tex.z-dn.net/?f=F%20%20%3D%2045%5Eo)
Lastly, the angle at E
--- angles in a triangle
Make E the subject
![E = 180^o - D - F](https://tex.z-dn.net/?f=E%20%3D%20180%5Eo%20-%20D%20-%20F)
![E = 180^o - 70^o - 45^o](https://tex.z-dn.net/?f=E%20%3D%20180%5Eo%20-%2070%5Eo%20-%2045%5Eo)
![E = 65^o](https://tex.z-dn.net/?f=E%20%3D%2065%5Eo)

Answer:
1/2
Step-by-step explanation:
I think so im not sure tho so sorry if its incorrect
The circumference of a circle is 2PiR.
Since we're just left with 8Pi, we can divide 8 by 2 to get the Radius.
Our radius is 4.
