Mohon dijawab… >_<​

Jawaban:

40°

semoga membantu

Penjelasan dengan langkah-langkah:

• 90=5x+5x-10

90+10=10x

100=10x

100÷10=x

10=x

•Maka Sudut IJL sebesar

=5x-10

=5(10)-10

=50-10

=40°

Jawaban:

Siku² = 90

5x + 5x – 10 = 90

90 + 10 = 100

5x + 5x = 10x

10x = 100

x = 10

Sudut IJL =

5x – 10

5 x 10 = 50 – 10 = 40°

IJL = 40°

Sudut LJK =

5x =

5 x 10 = 50

LJK = 50°

maaf kalo salah
