Question

in the given figure,find the value of 2a +b​

Answer 1

b+45+35=180°(sum of three sides of a triangle)

b+80=180

b=180-80

b=100

Now,

a=45°(being alternate angles are equal)

Again,

2×a=2×45=90°

b=100°

2a+b=90+100=190°

Answer 2

Answer:

200

Step-by-step explanation:

In Triangle

45+35+b=180(Angle sum property of triangle)

b=110 degree

a =45(alternate interior angles)

2a+b

=90+110

200
