2) 5.2 m

3) 11.1 m

Step-by-step explanation:

Question 2

The given figure is a Right Angled Triangle. From the figure we can see that the length of legs of the triangle is known and the length of hypotenuse is to be found. We can use Pythagoras Theorem to find the length of hypotenuse in a Right Angled Triangle.

According to the theorem:

$\textrm{(Hypotenuse)}^{2}=\textrm{(Leg 1)}^{2}+\textrm{(Leg 2)}^{2}$

From figure we can see the length of legs is 2.4m and 4.9m. Using these values in the above equation, we get:

$\textrm{(Length of Guy Wire)}^{2}=(2.4)^{2}+(4.6)^{2}\\\\ \textrm{(Length of Guy Wire)}^{2}=26.92\\\\ \textrm{(Length of Guy Wire)}=\sqrt{26.92}=5.2$

Thus, the length of guy wire will be 5.2m

Question 3:

We are given the rise and the run of the ramp. From the figure we can see that a Right Angled Triangle is being formed and the two known sides form the legs of the triangle and length of the ramp is represented by the hypotenuse. Again here we can use the Right Angled Triangle to find the missing length.

So,

$\textrm{(Length of Ramp)}^{2}=(10.5)^{2}+(3.5)^{2}\\\\ \textrm{(Length of Ramp)}^{2}=122.5\\\\ \textrm{(Length of Ramp)}=\sqrt{122.5}=11.1$

Therefore, the length of the ramp is 11.1 meters.

Answer from: shyiere4068

2) The length of guy wire = 5.4

3) The length of ramp = 11.1

Step-by-step explanation:

Points to remember

Hypotenuse² = Base² + Height²

2). To find length of guy wire

From the figure we can see a right angled triangle

Here hypotenuse = length of guy wire

Hypotenuse² = Base² + Height²

= 2.4² + 4.9² = 29.77

Hypotenuse = √29.77 = 5.4

Therefore length of guy wire = 5.4

3)To find the length of ramp

From the figure we can see a right angled triangle

Here hypotenuse = Ramp length

Hypotenuse² = Base² + Height² = 10.5² + 3.5² = 122.5

Hypotenuse =√122.5 = 11.06 = 11.1

Therefor length of ramp = 11.1

Answer from: Quest

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
