Question

Find the value of x in the given below triangles.​

Answer 1

In 1st triangle

by angle sum property (ASP)

60+70+x=180

130+x=180

x=180-130

x =50

In 2nd triangle

by ASP

30+90+x=180

120+x=180

x=180-120

x=60

Hope this helps ✌✌

Answer 2

Answer:

in figure 1,value of 2 angles are given ,we need to find value of x

we know that sum of angles of triangle is 180

=70+60+x=180

=130+x=180

=180-130=x

=x= 50

in figure 2,2 angles are given ,we need to find value of x

we know that sum of angles of triangle is 180

=30+90+x=180

=120+x=180

=180-120=x

60=,x
