Answer:
(b) the unknown angle is 80°
Step-by-step explanation:
The unkown angle is:
[2(x-10)]°
Substituting "x" by 50 (part a)
[2(50-10)]°=[2(40)]°=80°
Answer:
P(A^B) = 22/15 or 1 7/15
Step-by-step explanation:
To find the P (A^B), we add the probability of events A and B.
2/3 + 4/5 = P, we need to find the LCD to add disimilar fractions
LCD is 15.
2(5)/15 +4(3)/15 = 10/15 + 12/15 = 22/15
The square of 1,290 is 35.496.
