Answer 1

Soal Nomor 3

Materi : Kesebangunan dan Kekonggruenan

HF/HI = GF/GE

HF/6 = 10/24

HF = 6 × 10/24

HF = 10/4

{ HF = 2,5 } { d. }

Soal Nomor 4

Materi : Garis dan Sudut

∠P + ∠Q = 180°

( 3x ) + ( 4x + 26° ) = 180°

7x = 180° - 26°

7x = 154°

x = 154°/7

{ x = 22° }

Maka { ∠Q = ( 4x + 26° ) = 88° + 26° = 114° } { c. }

Soal Nomor 5

Materi : Garis dan Sudut

∠A3 = ∠B3

Cari Besar ∠A3

∠A3 + ∠A2 = 180°

5x + 4x = 180°

9x = 180°

x = 180°/9

x = 20°

Maka { ∠A3 = 5x = 100° }

Langsung Saja

∠B3 = ∠A3

8p = 100°

p = 100°/8

{ p = 12,5° } { a. }

Semoga bisa membantu

Answer 2

No. 3.

HI = 6cm

GE = 24cm

GF = 10cm

HF...?

24 HF = 6 × 10

24 HF = 60

HF = 2,5cm(D.)

No. 4.

P+q=180°

3x+4x+26=180

7x+26=180

7x=180-26

7x=154

x=22°

p=3x

p= 3 x 22

p=66°

q=4x+26

q=4(22)+26

q= 114°(C.)

No. 5.

∠A₂ + ∠A₃ = 180°

4x + 5x = 180°

x = 20°

Karena ∠A₃ dan ∠B₃ sehadap, maka

∠B₃ = ∠A₃

8p° = 5x

8p° = 5 × 20

p = 12,5°(A.)
