Because angles in a triangle add up to 180, you can add up the given angles and then take that answer away from 180, so:
65 + 74 = 139
180 - 139 = 41°
So your answer is 41°, I hope this helps!
200 is 2 *100 im sorry this is random
I believe you would take (114*34*2)+(114*1*2)+(1*34*2) equals 8048 squared feet of wrapping paper. I could be wrong. I found the areas of each side and added them together to get a total
Answer:
D) 140°
Step-by-step explanation:
The total number of degrees in a triangle is 180. Since both sides of the triangle are the radius of the circle, the triangle is isosceles. Therefore the two opposite angles are equal. Thus, the central angle is 180° − 2(20°) = 140°.
