What is the angle of elevation from b to a

∠2

Step-by-step explanation:

The angle of elevation is the angle between the horizontal line and the upward line of sight.

The angle of elevation from point B to point A is ∠2 as it sits between the horizontal and the line of sight that goes up to point A.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
