Could i get some on this question?

The triangles are similar, because the angles are congruent and the sides are proportional.

Step-by-step explanation:

The first step to see if the triangles are similar is to see if the angles are the same.

The third angle in the large triangle is

30 + 65+ unknown = 180

95 + unknown = 180

Subtract 95 from each side

unknown = 180-95

unknown = 85

So the angles are the same.

Lets check the ratio of the the sides

14            10

=

7                5    

Both simplify to 2/1  so the ratio's are the same.

The triangles are similar because the angles are congruent and the sides are proportional.

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
