It is useful to determine the distance the swing is below the pivot point when it is at its highest point of travel. That distance is

... 7 m + 0.8 m - 3.4 m = 4.4 m

The the cosine of the angle of interest is

... cos(θ) = 4.4/7

... θ = arccos(4.4/7) ≈ 51.055°

The angle is about 51°.

Given: NM ∥ XZ Prove: △XYZ ~ △NYM Triangles X Y Z and N Y M are shown. Triangle X Y Z is smaller and sits inside of triangle N Y
elena-s [515]

Answer:

Parallel

corresponding angles theorem

NYM

AA

Step-by-step explanation:  I DID IT ON EDGE! : )

We know that side NM is  _________________

✔ parallel

to side XZ. If we consider side NY the transversal for these parallel lines, we create angle pairs. Using the  _____________

✔ corresponding angles theorem

, we can state that ∠YXZ is congruent to ∠YNM. We know that angle XYZ is congruent to angle  _____________

✔ NYM

by the reflexive property. Therefore, triangle XYZ is similar to triangle NYM by the  _____________

✔ AA

 similarity theorem.

3. Sоlvе з+2У-1 and x-2y = 13. (D)<br>ху<br>ху​
sp2606 [1]

Answer:

The value of x and y for the given two linear equation is x = 7 , y = - 3

Step-by-step explanation:

Given two linear equation as :

x + 2 y - 1 = 0            

Or, x + 2 y = 1               ..........A

x - 2 y = 13                    ............B

Now, Solving both equations A and B

i.e (x + 2 y) + (x - 2 y) = 1 + 13

Or, (x + x) + (2 y - 2 y) = 14

Or, 2 x + 0 = 14

Or, 2 x = 14

∴ x = \dfrac{14}{2}

i.e x = 7

Now, Put the value of x into eq A

So, 7 + 2 y = 1

Or, 2 y = 1 - 7

Or, 2 y = - 6

∴  y = \dfrac{- 6}{2}

i.e y = - 3

So, The value s of x = 7 and y = - 3

Hence, The value of x and y for the given two linear equation is x = 7 ,          y = - 3 Answer
