firdahafizah Jumlah sudut segitiga = 180 derajat

(i) 2a + 3a + $35 ^{o}$ = $180^{o}$
= 5a + $35 ^{o}$ = $180^{o}$
= 5a = $180^{o}$ - $35 ^{o}$
= a = $\frac{145 ^{o} }{5}$
= $29^{o}$

(ii) 2b + 2b + 2b = $180^{o}$
6b = $180^{o}$
b = $\frac{ 180^{o} }{6}$
= $30^{o}$

(iii) 3c + c + c = $180^{o}$
5c = $180^{o}$
c = $\frac{ 180^{o} }{5}$
= $36^{o}$

Ridafahmi (i) 2a +3a +35 = 180
5a = 125
a = 125/5 = 25
(ii) 3(2b) = 180
6b = 180
b = 180/6 = 30
(iii) 3c +c + c = 180
5c = 180
c = 180/5 = 36
