What are the values of the variables in the triangle below? if the answer is not an integer, leave it in simplest radical form. the diagram is not drawn to scale

b.

Step-by-step explanation:

The diagram shows the right triangle with an acute angle of

In right triangle, the leg opposite to the angle is half the hypotenuse, so

By the Pythagorean theorem,

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
