1. 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
2. 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

3. 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.
I hope this helps ^^

5. 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 ...

14. 8. A 12 m ladder is lean on a wall. The top of the ladder can reach 4 m height of the wall. The distance between the bottom of the ladder and the bottom of the wall is … m. A8√2 B16√2 C4√10 D16√10
Jarak antara dasar tangga dengan dasar dinding adalah [tex] 8\sqrt{2} \: \text{ m} \: \: (\bold{A}) \: \:. \\ \\ [/tex]
PEMBAHASANBerdasarkan 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]
