Answer:
x = 21.4
Step-by-step explanation:
We need to use the law of sins
sin 42 sin x
--------- = ----------
22 12
12 sin 42 = 22 sin x
12 sin 42 /22 = sin x
Taking the inverse sin of each side
sin^-1(12/22 sin 42) = sin^-1(sin x)
21.40637223 =x
To the nearest tenth
x = 21.4
-5, because subtracting a negative is the same as adding a positive, which will bring -9 up to -5
Answer:
52
Step-by-step explanation:
40% of 130 is 52
We are given the probability of rain tomorrow of 60 % and a 40% chance of wind and rain. we are asked for the probability that it is windy, given that it is rainy. The formula that should be used is the quotient of the probability with "and" over the probability of the rain only. Hence, <span>P[W U R ] / P [R] = 0.4 / 0.6 = 2/3 = 67%</span>
