Question

in the figure if a-b=100 then what are the measures of a and b​

Answer 1

Answer:

a = 140° & b = 40°

Step-by-step explanation:

a - b = 100 => a = 100 + b

We know that Angle made by straight line is 180, i.e., whenever we construct a 180-degree angle, it always forms a straight line

∴ a + b = 180

=> (100 + b) + b = 180 (substituting a = 100 + b, from above equation)

=> 100 + 2b = 180

=> 2b = 180 - 100 = 80

=> b = 80/2 = 40

=> a = 100 + b = 100 + 40 = 140
