Answer:

A

Step-by-step explanation:

We know that MN = MQ, which makes triangle MNQ an isosceles triangle. By definition, then, ∠MQR = ∠MNR and the height from the vertex of the triangle (point M) to the base (QN) is perpendicular and bisects ∠QMN. In other words, ∠QMR = ∠NMR = 36°.

Now, since QMR is a triangle, all three angles add up to 180, so we can find the angle MQR:

∠MQR = 180 - 36 - 90 = 54°

Now, since PQ = NO, we can say that PQNO is an isosceles trapezoid, so by definition, ∠PQN = ∠ONQ. And, since ∠MQR = ∠MNR = 54° and ∠MNO = 125, we can find ∠PQN = ∠ONQ:

∠PQN = ∠ONQ = 125 - 54 = 71°

Since PQRS is a quadrilateral, by definition, all angles will add up to 360. So, we have:

∠PQR + ∠QRS + ∠RSP + ∠SPQ = 360

71 + 90 + 90 + ∠SPQ = 360

∠SPQ = 109

Since ∠SPQ is the same angle as ∠OPQ, the answer is A.

(a) 2x + 5x + 4 = 25 <== ur equation
    7x + 4 = 25
    7x = 25 - 4

Solve the problem.
marta [7]

Answer:

There will be 90 ways to reach Greenup from Charleston.

Step-by-step explanation:

<em>Option C: 90 is correct.</em>

Let's name all the ways and try to visualize the roads.

C = Charleston

M = Mattoon

T = Toledo

G = Greenup

Task = Charleston to Greenup. How many different ways to reach?

    1            1          

    2           2           1

C   3     M   3   T      2   G

     4           4           3

     5           5

                   6

So, Refer to this above diagram.

If we Start from C then go to 1 and then go to M and then go to 1 and then go to T and then go to 1 and then go G.

If you notice, in this single possibility we have 3 ways: C to 1 to M, M to 1 to T, T to 1 to G.

It means we will have: 5 x 6 x 3 = 90 number of ways to reach greenup from Charleston.

S: (2,10)

E: (6,10)

Step-by-step explanation:

the image on the grid is after doin x- 1 and y-7

to get the preimage do the inverse , x + 1 , y + 7

note- a coordinate is written as (x,y)

so, add 1 to all the x's and 7 to all the y's on the coordinates on the grid!

and sorry for asking but, if this is right could i please get a thanks & brainliest recently a moderator deleted ALL my answers (over 400 answers) causing me to lose over 3k points so id appreciate it alot thanks xoxo
