Answer with explanation:

It is given that,

ΔABC ≅ ΔG E F--------------[A S A]

→→When two triangles are congruent , corresponding angles as well as Corresponding Sides, are equal.

→≡Corresponding Sides

1. AB=GE

2. BC=E F

3. AC=G F

→≡Corresponding Angles

1. ∠A=∠G

2. ∠B=∠E

3. ∠C=∠F

Option C: →∠CAB=∠E G F

Answer:

$\boxed{\sf \ \ \ m = -\dfrac{tn}{t-s} \ \ \ }$

Step-by-step explanation:

Hello,

let s assume that m+n is different from 0

we have this equation and we need to find m as a function of t, s, and n

$t=\dfrac{ms}{m+n}$

<=>

$(m+n)*t=ms\\\\ tm+tn=sm\\ (t-s)m = -tn\\ m = -\dfrac{tn}{t-s}$

for t-s different from 0, so t different from s

hope this helps

M is the midpoint of QR M = (-2,6) Q= (8,-10) R = ????

Zolol [24]

Answer:

R = (-12, 22)

Step-by-step explanation:

Unfortunately it's not a straight line, so gonna need to put in some extra work. Basically think of it like breaking it into it's horizontal and vertical components then doubling them.

From Q to M you move 10 spaces to the left, so to go from M to R you will go another 10 to the left. Similarly, you start at -10 for the y value and go up 16 to 6, and you will need to go up another 16 to get to R.

So for x, 8 -10 = -2 then -2 - 10 = -12, so R's x value is -12

y we do the same thing. Gonna do it in one step though. -10 + 16 + 16 = 22

So R is (-12, 22)
