The probability that the second slip will contain an obtuse angle measure, given the first slip contained an acute angle measure is 3/4.
What is conditional probability ?Conditional probability is occurrence of a certain event based on the occurrence of the previous event.
According to the given question the angle measures 30°, 60°, 120°, and 150° are written on slips of paper.
One student chooses a slip, identifies the type of angle, and returns the slip.
Let A = Choosing an obtuse angle in the second time and B = Choosing an acute angle in the first draw.
Now, P(A/B) = Probability of choosing an obtuse angle when the first draw was an acute angle.
P(A) = 1/2 and P(B) = 2/3.
∴ P(A/B) = (1/2)/(2/3) = 1/2×3/2 = 3/4.

The surface area is the 2-dimensional distance around a 3-dimensional figure. In essence, if one was going to wrap a figure in paper, the surface area is the amount of paper one would need. To calculate the surface area one needs to find the area of each face of the figure, then add up all of the values.

Step-by-step explanation:
[tex] \sin(x) = \frac{7}{15} \\ x = { \sin}^{ - 1} ( \frac{7}{15} ) \\ x = 27.8 \degree[/tex]
Answer:
28°
Step-by-step explanation:
For this problem, we are given the leg length opposite the angle x and the hypotenuse. This perfectly describes the trig function, sine. We can set up an equation:
opposite / hypotenuse = sin(x°)
We can substitute in the sides:
7 / 15 = sin(x°)
Now, to find x, we can evaluate the inverse of sin or arcsin on the ratio 7 / 15
arcsin(7 / 15) = x° = 27.81813928°
This rounds to 28°
