Question

Bantu lagi ya
Pada segitiga sembarang PQR, diketahui :
P = 3c°
Q = c°
R = c°
Tentukan nilai c ?
Hitung besar

Answer 1

P + Q + R. = 180
3c+ c +c = 180
5c = 180
c = 180/5
c = 36 derajat

semoga membantu :)

Answer 2

<P + <Q + <R = 180°
3c° + c° + c° = 180°
5c° = 180°
c = 180/5
c = 36

<P = 3 × c°
<P = 3 × 36
<P = 108°

<Q = c°
<Q = 1 × 36
<Q = 36°

<R = c°
<R = 1 × 36
<R = 36°
