Tentukan nilai P dan besar penyiku ∠BAD

Tentukan nilai P dan besar penyiku ∠BAD

Jawaban yang benar adalah p = 27° dan penyiku ∠BAD = 54°.

Pembahasan :
Sudut penyiku merupakan sudut-sudut yang berada pada suatu garis tegak lurus memiliki total sudut yang besarnya sama dengan 90°.

Jika A dan B saling berpenyiku, maka :
∠A + ∠B = 90°

Penyelesaian :
∠CAD + ∠BAD = ∠BAC
2p + 36° = 90°
2p = 90° – 36°
2p = 54°
p = 54°/2
p = 27°

Penyiku ∠BAD = ∠CAD
= 2p
= 2(27°)
= 54°

Jadi, nilai p dan besar penyiku ∠BAD adalah 27° dan 54°.
