Find the question :-
1) find the value of a, b and c

Please mam answer it fast ​

Answer 1

Given: Triangle PQR
To find: The values of angle a,b,c
Solution: Sum of all the angles in a triangle is equal to 180 degrees.
So value of angle a = 65 degree
Since angle a and angle b are linear pair of angles. Therefore angle b = 180-65=115 degree
Now value of angle c = 180-115-40= 25 degree
Angle a= 65 degree
Angle b= 115 degree
Angle c = 25 degree

Answer 2

Answer:

a=65,b=115,c=25

Step-by-step explanation:

55+60+a=180

a=180-115

a=65

a+b=180

65+b=180

b=180-65

b=115

40+b+c=180

40+115+c=180

c=180-155

c=25
