Question

in triangle ABC a+b=70° and b+c=135°. find the measure of each angle of triangle

Answer 1

Heres your answer

According to the theorem sum of angles of an triangle is 180°

So

a+b+b+c=180

70+135=180

205= 180

=180- 205

=25

So the sum of each angle of triangle is 25°

Hope it Helps!!

Answer 2

a+b+c=180 (Angle sum property)
70+c=180
c=110°

Similarly,a+135=180
a=45°

we found c and a
Now, a+b+c = 180 (Angle sum )
110+45+b=180 (Angle sum)
b=25
Hope it helps^_^
