Kwahiyo unataka nini maana majibu tayari

Kwahiyo unataka nini maana majibu tayari

sijalielewa, how can this ladder make two angles to the horizontal?

Mkuu hv SOTOCA/HAH hukusoma ukaielewa!?....

Hilo swali ni rahis kuliko neno lenyewe

(a)11.3m

Since the ladder makes an angle of 75.17 degrees with the horizontal, we can write:
tan(75.17)=x3
Solving for x, we get:
x=tan(75.17)3
Now, using the Pythagorean theorem, we can write:
L2=x2+32
Substituting our expression for x into this equation and solving for L, we get:
L=(tan(75.17)3)2+32≈11.3m
So, this is how 11.3m is obtained as the length of the ladder.

(b)5.6m

the ladder makes angles of 75.17 and 60.45 degrees to the horizontal with 3m between the two angles. The length of the ladder is 11.3m and the distance from the foot of the ladder to the wall is 5.6m.

To show how 5.6m was obtained, we can use trigonometry.

Since the ladder makes an angle of 75.17 degrees with the horizontal, we can use the tangent function to find the distance from the foot of the ladder to the wall: tan(75.17) = opposite/adjacent.

The opposite side is the distance from the foot of the ladder to the wall (which we are trying to find), and the adjacent side is 3m (the distance between the two angles). Solving for opposite, we get: opposite = adjacent * tan(75.17) = 3 * tan(75.17) ≈ 5.6m.

Therefore, the distance from the foot of the ladder to the wall is approximately 5.6m.

Hebu eleza hiyo ladder inawezaje kuwa na hizo angle mbili kama hilo swali lipo sawa kabisa. Weka na diagram ukiweza.

weka diagram ya hayo maelezo kama swali lipo sawa kabisa hilo.

Asante,
japo njia imeleta jibu lakini haipo sawa na swali. Ndio maana hata angle ya pili hajatumia na hajatupa diagram.

Swali haliko Sawa mkuu. Sijui kama umelikopi Sawa au umetype vibaya. Kulingana na maelezo kwenye swali tayari ladder ina 3 m between the two angles 60.45 na 75.17.

Mguu was kushoto una angle hii na mguu wa Julia una angle ile

Mguu was kushoto una angle hii na mguu wa Julia una angle ile

ladder ya wapi hiyo? Weka diagram tuone

nimelikopi kama lilivyo ila nashangaa hawa jamaa wanasema simple halafu hawaleti diagram kuonesha lilivyo.

 

[FaizaFoxy]

sijalielewa, how can this ladder make two angles to the horizontal?

One angle at the top of the ladder and the other angle at the bottom of the ladder.

 

[crankshaft]

One angle at the top of the ladder and the other angle at the bottom of the ladder.

kwa hiyo condition basi those angles must add up to 90 degrees. Lakini hizi mbili zinazidi.
