Becouse k and n are 'neighbours' so their sum are 180
so k=180-42=138
Answer:
x = 5/3
Step-by-step explanation:
-3x+5
-5= -3x
-5/-3 = 5/3
Answer:
False
Step-by-step explanation:
Flip the equation.
−a<2
Divide both sides by -1.
a>−2
In what I know of this problem and what you told me I think there is a 1/2 chance!
think about it, if the life span is 15 years old with standard deviation of 3 then that means we can have bats from 12~18 years old and the mean of the 50 numbers can be anything between that depending on the results we got. Then half of values in interval 12~18 is over 15 which gives it a 1/2 probability!
The angle T1PT2 is 65-37=28 degree
use law of sine: sin37/PT2=sin28/7370, PT2=7370*sin37/sin28
Use a calcuator, I got the answer 9448
B. sin65=PA/PT2, PA=PT2*sin65=9448*sin65=8563
