Answer:

coordinates of B(2 , -5).

Step-by-step explanation:

Given  :  triangle ABC with vertices A (1,5) B (5,2) And C (-1,2) is rotated 90°.

To find : what are the coordinates of B.

Solution : We have given

Vertices A (1,5) B (5,2) And C (-1,2)  is rotated 90° .

By the rotation rule of 90° is  ( x , y ) →→ (y , -x).

Then coordinates of B ( 5, 2) →→ B'(2 , -5).

Therefore,  coordinates of B(2 , -5).

Assuming this is around the origin:

To find the rotation by 90 degrees, it would be (y, -x) (Assuming that the x and y are both variables and number figures)

So therefore, (5, 2) would become (2, -5).

I hope this helped! :)

ILL MARK BRAINIEST IF YOU CAN DO THIS RIGHT!!!

Answer:  Slope: -1/2  

Step-by-step explanation:  To find slope take 2 points that lie on the line and use this formula to solve:  <em> </em>I will use (0, -2) and (2, -3) to solve

                                                                       ↑    ↑           ↑   ↑

y2 - y1                                                             x1  y1          x2  y2

-----------

x2 - x1

So, for this question, substitute the x and y values from the points above to solve.

-3 - (-2)      

----------- =  - 1/2

2 - 0

Hope this helped. :)

Find m∠I. Put the answer below.<br> m∠I =
pashok25 [27]

Answer:

The answer is 68°

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • A right angled-triangle IGH.
  • where, m∠G = 90°
<h3><u>To </u><u>Find</u>;</h3>
  • m∠I = ?

We know that

tan θ = Opp ÷ Adj

tan θ = 5 ÷ 2

tan θ = 2.5

tan θ = 68.2 ≈ 68

We know that tan 68 = 2.5

Thus, The m∠I is 68°

Simplify the following: (r+s-t)-(r-s+t)
ArbitrLikvidat [17]
R+s-t-(r-s+t)

=2s-t is the answer



People think this answer would be just =2s but I have verified with an online calculator and the answer that textbooks look for regarding this is 2s-t

You would assume you would go r-r and thats 0 so no r's

you would say s-(-s) makes it plus and theres 2s

and you would say -t -(+t) is -t 

that's why the answer is 2s-t

At first I also did t-(+t) and thought it would be no t's but the answer is in fact 2s-t
