Question 2 I need help w that

101°

Step-by-step explanation:

The interior angles indicated add up to the exterior angle <KMN because they are on the opposite side of it. You can substitute these into an equation to find x.

4x + 81 = 13x + 36

Group like terms

4x - 13x = 36 - 81

-9x = -45

Divide both sides of the equation by -9 so x can stand alone

x = 5

Now to find <KMN, we just have to substitute 5 into the expression

= 13(5) + 36

= 65 + 36

= 101°

∠KMN = 101°

Step-by-step explanation:

Exterior angle of a triangle equals to the sum of opposite interior angles.

13x + 36 = 4x + 81

Subtract 4x from both sides

13x + 36 - 4x = 4x + 81 -4x

9x + 36 = 81

Subtract 36 form both sides

9x + 36 - 36 = 81 - 36

           9x = 45

Divide both sides by 9

 9x/9 = 45/9

 x = 5

∠KMN = 13x + 36

           = 13*5 + 36

          = 65 + 36

∠KMN = 101°

can you add an image ?

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
