Answer:
28.7
Step-by-step explanation:
a^2 + b^2 = c^2
25^2 + 14^2 = 821
Square root of 821 is 28.7.
Answer:
( i ) ∠AOB = 72
( ii ) ∠BOC = 67
( iii ) ∠COD = 134
( iv ) ∠AOD = 87
Step-by-step explanation:
Sum of angles in a circle is 360,
a + b + c + x = 360
72 + 67 + 134 + x = 360
273 + x = 360
x = 360 - 273
x = 87
∠AOB = a = 72
∠BOC = b = 67
∠COD = c = 134
∠AOD = x = 87

The answer to this specific formula is 2
Answer:
Probability that it is a red card: 50%
Probability that it is a black card: 50%
Step-by-step explanation:
You have an even probability of getting a red card or a black card. This is true because there are an even number of red cards and black cards. (25 or 26 of each, depending on if you include jokers.) Therefore, there is an even probability of getting a red card or a black card. It has to be 50%, because that is the only number in which two options can have equal numbers.
Hope this helps! :D
