Answer:
radius = 21
Step-by-step explanation:
Answer:
180 - 62 - 57 = 61
∠BAD = 180 - 61
∠BAD = 119°
Step-by-step explanation:
85 = 10x+15
70 = 10x
x = 7
180-85 = 95 = z
Eleven Twentieths of the pie are left, so that's 11/20
Method to solve;
Since its given a 1/4 and a 1/5 it's easiest to convert these to twentieths (the lowest common multiple of 4 and 5)
So 1/4= 5/20
1/5 = 4/20
How much is eaten = 5/20 + 4/20 = 9/20
How much remains = Total (20/20) - How much eaten (9/20) = 11/20
