Question

In triangle abc if a + b equal to 125 and a + c equal to 113 find angle a b and c

Answer 1

a+b=125

a+c=113

a+b+c=180

a+b=180-c  

180-c= 125

c=55

a+55=113

a=58

Answer 2

Answer:

Step-by-step explanation:

given a + b = 125 , a + c = 113

we know that sum of all angle in triangle = 180

so,

a + b + c = 180

125 + c = 180

c = 55

a + c = 113

a = 58

a + b = 125

58 + b = 125

b = 67

so a = 58, b= 67, c = 55
