Answer 1

Answer:

first -

in triangle ADC

DAC + ADC + ACD = 180

60 + C + 70 = 180

C = 180 - 130

C= 50

C IS EQUAL TO THEIR FAREST ANGLES SUM

ADC = BAD + ABD

50 = 30 + ABD

ABD = 20

THE IN TRIANGLE BDA

ABD + BAD + ADB = 180

20 + 30 + ADB = 180

ADB = 180 - 50

ADB = 130

SO a = 20

b = 130

and c = 50
