This is what I got as the answer, 2b x (12-17a)
5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
Answer:
{21, 22, 23, 24}
Step-by-step explanation:
m>20 means that m is greater or more than 20, therefore 21, 22, 23, and 24 are all greater than 20 so that is the answer.
Perpendicular from the center to the chord, bisects it!
DE = DF/2 = 12
To find R, use Pyth Th in triangle AOB. ( AB = 10)
10^2 + 14^2 = R^2
100+ 196 = 296 = R^2
In triangle DOE
x^2 + 12^2 = 296
x^2 = 296-144 = 152
x = √152
x = 12.3
