Answer:
fourth option
Step-by-step explanation:
Using the Law of Cosines in Δ STU to find s
s² = t² + u² - 2us cosS
where t = 9, u = 10 and S = 100° , thus
s² = 9² + 10² - 2(9)(10)cos100°
Answer:
Value of x is 80 and yes they are vertical
Step-by-step explanation:
The probability of getting heads on the first toss is 1/2 .
Then, the probability of getting heads on the second toss is 1/2 .
Then, the probability of getting heads on the third toss is 1/2 .
The probability of all three things happening is ...
(1/2) x (1/2) x (1/2) = 1/8 = 0.125 = 12.5% .
