Answer:
cos P = 53 degrees
cos Q = 37 degrees
Step-by-step explanation:
cos P = 
cos P = 
cos P = 0.60
Cos-1 of 0.60 is 53.13 (round to the nearest whole number)
cos P = 53 degrees
cos Q =
cos Q = 
cos Q = 0.80
Cos of 0.80 is 36.86 (round to the nearest whole number)
cos Q = 37 degrees
To check anser:
90 + 53 + 37 = 180
180 = 180
You just have to think what is 40% of 100 which is 40 then multiply 40 2 times to find out the answer four 40% of 200 when you do 40x2 it =80 so the answer is 80
Answer:
B) -6
Step-by-step explanation:
Placing a minus sign outside absolute value bars gives you a negative result For example, –|6| = –6, and –|–6| = –6.
11 - 2/3n = 4 + n
n + 2/3n = 7
3n^2 + 2 = 21n
3n^2 - 21n + 2 = 0
n = 6.903 , n = 0.09657
