Answer:
small c in triangle ADC equals 110
small b in triangle ADB is 70
small a in triangel ABD equals to 80
small a in triangle PSQ is 119
small b equals in triangel PSR 61
small c in triangel RPS is 79
Explanation:
triangle ABC
ADC angel is 60+10=70 ,, 180-70= 110
small c in triangle ADC equals 110
ADB angel is 180-110=70
small b in triangle ADB is 70
ABD angel is 70+30=100 ,, 180-100=80
small a in triangel ABD equals to 80
triangel PQR
PSQ angel is 55+6=61 ,, 180-61=119
small a in triangle PSQ is 119
small a + small b = 180
119+ b = 180
180-119=61
small b equals in triangel PSR 61
RPS angel is 40+61=101 ,, 180-101= 79
small c in triangel RPS is 79
