Question

If p,q and r are the angle of triangle and p+q=100 ° then r=

Answer 1

Step-by-step explanation:

p+q+r=180

100+ r =180

r=80

Answer 2

Answer:

80

Step-by-step explanation:

sum of a triangle = 180°

sum of a triangle = 180°then

sum of a triangle = 180°thenp+q = 100

sum of a triangle = 180°thenp+q = 100 .

sum of a triangle = 180°thenp+q = 100 .. . p+q+r = 180

sum of a triangle = 180°thenp+q = 100 .. . p+q+r = 180 100+r =180

sum of a triangle = 180°thenp+q = 100 .. . p+q+r = 180 100+r =180 r= 180-100

sum of a triangle = 180°thenp+q = 100 .. . p+q+r = 180 100+r =180 r= 180-100 = 80
