Question

In a triangle, one angle is 80°. The second angle
is half of this. Find the measures of the second
and third angle of the triangle.

please tell this answer...​

Answer 1

Step-by-step explanation:

1st angle = 80°

2nd angle = 80°/2 = 40°

3rd angle = x(Say)

1st+2nd+3rd = 180°

80°+40°+x = 180°

80+40+x = 180

120+x = 180

x = 180-120

x = 60

3rd angle = x = 60°

Answer 2

Answer:

The third angle is 60°

Step-by-step explanation:

First angle = 80°

The second angle = half of the first angle =80\2= 40°

The area of triangle = 180°

So 80 + 40 + ___ =180

So 80+ 40 + 60 = 180
