Then the values of <A and <C will be respectively :
a) 70°,30° b) 30°,30° c) 80°,30° d) 50°,110°
please i need it before 9:30!!​

Answer 1

Answer:

(C) 80°,30°

Step-by-step explanation:

Adding both given equations

A + 2B + C = 250

As A+B+C = 180

180 + B = 250

B = 70

From given,

A = 150 - B

A = 150 - 70

A = 80

From given,

C = 100 - B

C = 100 - 70

C = 30
