2. The angle of elevation of a ladder leaning against a wall is 60º and the foot of the ladder is 4.6 m away from the wall. The length of the ladder is:

The length of the ladder
= 4,6 / cos a
= 4,6 / cos 60°
= 4,6 / (1/2)
= 4,6 . 2
= 9,2 m

Kelas 10 Matematika
Bab 6 Trigonometri Dasar< = 60°
x = 4,6 m
r = ...?

cos 60° = x/r
1/2 = 4,6/r
r = 4,6 / 1/2
r = 4,6 × 2
r = 9,2 m


so the length of the ladder is 9,2 m

Jarak antara dasar tangga dengan dasar dinding adalah [tex] 8\sqrt{2} \: \text{ m} \: \: (\bold{A}) \: \:. \\ \\ [/tex]

PEMBAHASAN

Berdasarkan informasi pada soal dapat diketahui bahwa sebuah tangga dengan panjang 12 m bersandar pada dinding dengan tinggi 4 m membentuk segitiga siku-siku. Alasnya merupakan jarak antara dasar tangga dan dasar dinding.

Misal [tex] a [/tex] adalah alas segitiga, [tex] b [/tex] adalah tinggi segitiga, dan [tex] c [/tex] adalah sisi miring segitiga.

Dengan menggunakan teorema Pythagoras maka berlaku

[tex] \begin{aligned} a^2+b^2 & \: = c^2 \\ \\ a^2 + 4^2 \: & = 12^2 \\ \\ a^2 \: & = 12^2 - 4^2 \\ \\ a^2 \: & = (12+4)(12-4) \\ \\ a^2 \: & = 16 \cdot 8 \\ \\ a^2 \: & = 128 \\ \\ a \: & = \sqrt{128} \\ \\ a \: & = 8\sqrt{2} \\ \\ \end{aligned} [/tex]

KESIMPULAN

Jarak antara dasar tangga dengan dasar dinding adalah [tex] 8\sqrt{2} \: \text{ m} \: \: (\bold{A}) \: \:. \\ \\ [/tex]

15. A ladder rests in 1,5 m tall with one end against a tree at a height of 4 m above the ground and the other end on the ground. If the wall is 0,5 m away from the bottom of the ladder, find the horizontal distance of the base of the tree from the bottom of the ladder

1,5 + 4 = 5,5
5,5 : 0,5 = 1,1
if not wrong so ...

16. the angle of elevation of a ladder leaning against a wall is 60 degrees and the foot of the ladder is 4.6 m away from the wall. the length of the ladder is ___ m. type your answer below!

Jawaban:

9.2 m

Penjelasan:

Angle = 60º and distance between wall and ladder= 4.6 m.

Length of ladder= 2 x distance between wall and ladder

= (2 x 4.6) m

= 9.2 m.
