Jawaban:
3. besar sudut PQR adalah 60°
4. besar <CBD 106°
5.a. ∠ROQ = 45˚
b. ∠SOR = 135˚
c. ∠POQ = 135˚
Penjelasan dengan langkah-langkah:
3.. < PQR + < SQR
2x + x= 90
x=
jadi besar sudut PQR
2x °
(2.30)°
= 60°
4. 5a+4°+7a+8°= 180°
12a+12°=180°
12a=168°
a=14°
<CBD= 7a+8°
= 7(14°)+8°
= 98°+8°= 106°
5. a. ∠ROQ = ∠SOP
∠ROQ = 45˚
b.∠SOR + ∠SOP = 180˚
∠SOR = 180˚ – ∠SOP
∠SOR = 180˚ – 45˚
∠SOR = 135˚
c. ∠POQ = ∠SOR
∠POQ = 135˚
semoga membantu jadikanlah jawaban cerdas
