Answer:

(4,3), (−4,8), (−4,3)

(2.5,−4), (0,0), (0,−4)

Step-by-step explanation:

On plotting on graph all form right angled triangle.

Dimension of all triangles and tanФ

  1. Base=2 Height=5   tanФ  2.5
  2. Base=5 Height=3   tanФ  1.6
  3. Base=8 Height=5   tanФ  1.6
  4. Base =2.5 Height=4   tanФ  1.6

[Here base and height can be interchanged if needed]

Ratio of perpendicular and base of last two triangle is equal.

First two are not congruent to any of other triangle but 3rd and 4th triangle are congruent .

Their coordinates are:

(4,3), (−4,8), (−4,3)

(2.5,−4), (0,0), (0,−4)

Solve for X. 20 points !!!!
GarryVolchara [31]

Answer:

4) x = - 12

5) x = 4

Step-by-step explanation:

4)

Since points T and S are mid points of sides ML and MN of triangle MLN.

Therefore, by mid point theorem,

TS is half of LN

so,

x + 26 =  \frac{1}{2} (x + 40) \\  \\ 2(x + 26) =x + 40 \\  \\ 2x + 52 = x + 40 \\  \\ 2x - x = 40 - 52 \\  \\ x =  - 12

5) In the same way x = 4 will be the correct answer in question number 5.
