Answer:

Option D

Yes. By AA~

Step-by-step explanation:

Given are two lines JMG and HMK intersecting at M.

To check whether two triangles are similar

Consider the two triangles HMG and JMK

We are going to compare the angles of the two triangles

We have

Angle H = angle K =39 (given)

Angle HMG = Angle JMK (Vertically opposite angles)

Since two angles of a triangle are congruent the third angle also will be congruent

Thus we find that the two triangles have AAA congruence

Hence the two triangles are similar by AA~.

Can someone explain this to me

Lynna [10]

Answer:

$\huge\boxed{\sf tan \ 28 = x / 14}$

Step-by-step explanation:

Since opposite and adjacent is given, we will use tan as trigonometric ratio.

Hence,

opposite = x , adjacent = 14 and $\theta$ = 28

So,

$\sf tan \theta = opposite / adjacent$

tan 28 = x / 14

$\rule[225]{225}{2}$

Hope this helped!

If an urn has 5 white balls 10 red balls what is the probability that 5 randomly selected balls contain exactly 3 white balls?

kondaur [170]

Answer:

0.15

Step-by-step explanation:

Without Mincing words let us dive straight into the solution to the question above. We are given the following information which is going to aid in solving this particular question.

====> It is given, that there are 5 white balls and 10 red balls. Hence, the number of the total balls = 5 white balls + 10 red balls = 15 balls.

Therefore, the probability that 5 randomly selected balls contain exactly 3 white balls = $\left[\begin{array}{ccc}5\\3\end{array}\right]$ × $\left[\begin{array}{ccc}10\\2&\end{array}\right]$ ÷ $\left[\begin{array}{ccc}15\\3\\\end{array}\right]$ = 450 ÷ 3003 = 0.15

The following graph represents an inequality.

Leni [432]

Answer:

Opt. 1 -3 ≤ x ≤ 3

Step-by-step explanation:

Inequalities are regions, the attached picture shows us a region located between -3 and 3, the dots used are solid, this means that the value '3' is include in the region.

Hence the variable is narrowed to -3 and 3.
