Answer:
130
Step-by-step explanation:
First, we know that BG is the diameter. So using that information, The right side and left side both measure 180 degrees in total.
Chrod DF and Diameter BG is a perpendicular bisector so that line segment DE equal Line segment EF.
Since DR equal EF, Arc DG and DF equal each other so that means DG measure 50 as well.
Arc BG measures 180 degrees we know 50 degrees part of that arc. We can use this equation
BD measures 130.
Answer:
a, and c
Step-by-step explanation:
His brother would be 7 years old.
Answer:
L
Step-by-step explanation:
interior angle formula so
(number of sides - 2)*180
2*180 = 360
you can also just take an example from a square 4*90 = 360
360-121-58-70 = 111
100 would be the nearest whole number
