kak tolong jawab pertanyaan 7 sampai 10 kak tolonggggg niannn kakkk

Soal No. 7
Segitiga Sama Kaki
∠M = ∠U = 70°
∠S = ∠T
Jumlah sudut segitiga = 180°
180° = ∠U + ∠S + ∠T
180° = 70° + 2∠T
2∠T = 180° - 70°
2∠T = 110°
∠T = [tex] \frac{110}{2} [/tex]
∠T = 55°................................Jawaban (c)

Soal No. 8
[tex] \frac{EF}{AB} = \frac{DE}{AD} \\ \\ \frac{EF}{18} = \frac{3}{8} [/tex]
8 × EF = 18 × 3
8 × EF = 54
EF = [tex] \frac{54}{8} [/tex]
EF = 6,75 ............................Jawaban (a)

Soal No. 9
Ketiga dari Segitiga Siku-siku tersebut adalah kongruen.
BF = EG = sisi tegak segitiga siku-siku
Sehingga BF = EG = 16 cm².................. Jawaban (c)

Soal No. 10
AE = CD = 10 cm
BE = BC = 6 cm
AB = √(AE² - BE²)
AB = √(10² - 6²)
AB = √(100 - 36)
AB = √64
AB = √8²
AB = 8 cm

Luas Segitiga = [tex] \frac{1}{2} [/tex] × Alas × Tinggi
                         = [tex] \frac{1}{2} [/tex] × 6 × 8
                         = 3 × 8
                         = 24 cm²..........Jawaban (a)
