Jika suatu segitiga sudut-sudutnya berbanding 1 : 2 : 3 maka besar sudut terbesarnya adalah .... TOLONG DI JAWAB YA BUK/PAK...
Jumlah sudut-sudut segitiga adalah 180°, mis: sudut-sudutnya 1x; 2x dan 3x
x + 2x + 3x = 180°
6x = 180°
x = 180° : 6
x = 30°, jadi besr sudut yang terbesar adalah 3 x 30° = 90°
Zendi, ditunggu pertanyaan yang laen yaaaa...
Pada persegi EFGH diketahui panjang diagonal EG = (3x-4) cm dan FH = 20cm.
Pertanyaan : Tentukan nilai x dan panjang diagonalnya.
tolong dijawab ya...!!!
Karena EFGH persegi maka panjang diagonalnya sama panjang, maka
EG = FH
3x – 4 = 20
3x = 20 + 4
3x = 24
x = 24 : 4
x = 8 cm
Jadi panjang diagonalnya 8 cm.
Gitu ya Zendi... met belajar yaaa...
a.1per3 sudut lurus
b.1per3sudut satu putaran penuh
c.1 1per2 sudut siku siku
a. 1/3 ( 180° ) = 60°
b. 1/3 ( 360° ) = 120°
c. 1 1/2 ( 90° ) = 135°
Gitu ya Gio.... met belajar yaaa...
Jika besar sudut x = 34° dan y = 2a° kedua sudut tersebut saling berpenyiku, maka a° adalah.....
Karena saling berpenyiku maka, x + y = 90°
34° + 2a = 90°
2a = 90° – 34°
2a = 56°
a = 56° : 2
a = 28°
Gitu ya mas Bagus.... met belajar yaaa... sukses selalu.
the measure of an angle is 5 times the measure of its supplement. find the measure of that angle.
Misal besar sudut tersebut adalah x, dan pelurusnya 180° – x.
Jadi x = 5 ( 180° – x )
x = 900° - 5x
x + 5x = 900°
6x = 900°
x = 900° : 6
x = 150°
Jadi ukuran sudut tersebut 150° dan pelurusnya 30°
Gitu ya Rama....met belajar yaaa....
pak/bu mohon bantuannya ya

assalamualaikum bapak atau ibu guru sekalian..
saya ingin bertanya, bagaimana cara menyelesaikan soal mtk ni,soalnya saya kurang paham atas soal ni, mohon bantuannya untuk dijwab soal sebagai berikut ;
1. jika sin a + sin B = k dan cos a + cos b = m, buktikan :
a. k+m = 2 cos 1/2 (a-b) [sin 1/2 (a+b) + cos 1/2 (a+b)]
b. k = m tan 1/2 (a+b)
c. k(kuadrat)+m (kuadrat) = 2 [1=cos (a-b)] = 4 cos(kuadrat)1/2(a-b)
2. buktikan bahwa :
4 sin 18 cos 36 sin 54 = 1+2 sin 18-cos 36
mohon bantu dijawab ya.kalau bisa secepatnya
terimakasih
wassalamualaikum

The Blonde and the Lawyer
A blonde and a lawyer are seated next to each other on a flight from LA to NY. The lawyer asks if she would like to play a fun game.
The blonde, tired, just wants to take a nap, politely declines and rolls over to the window to catch a few winks.
The lawyer persists and explains that the game is easy and a lot of fun.
He explains, “I ask you a question, and if you don’t know the answer, you pay me $5.00, and vise versa.”
Again, she declines and tries to get some sleep. The lawyer, now agitated, says, “Okay, if you don’t know the answer you pay me $5.00, and if I don’t know the answer, I will pay you $500.00.”
This catches the blonde’s attention and, figuring there will be no end to this torment unless she plays, agrees to the game. The lawyer asks the first question. “What’s the distance from the earth to the moon?” The blonde doesn’t say a word, reaches into her purse, pulls out a $5.00 bill and hands it to the lawyer. “Okay” says the lawyer, “your turn.”
She asks the lawyer, “What goes up a hill with three legs and comes down with four legs?” The lawyer, puzzled, takes out his laptop computer and searches all his references, no answer. He taps into the air phone with his modem and searches the net and the library of congress, no answer. Frustrated, he sends e-mails to all his friends and coworkers, to no avail. After an hour, he wakes the blonde, and hands her $500.00.
The blonde says, “Thank you”, and turns back to get some more sleep.
The lawyer, who is more than a little miffed, wakes the blonde and asks, “Well, what’s the answer?” Without a word, the blonde reaches into her purse, hands the lawyer $5.00, and goes back to sleep.
