Question

Calculate the size of a and b respectively in the diagram below

Answer 1

Answer:

angle a=80

angle b=100

Step-by-step explanation:

assumption the second and third angle is 65 & 35.

sum of angle of triangle= 180

hence,

180 = a+ 35+ 65

a= 180-100= 80

now, sum of angle a&b(linear pair)= 180

hence,

a+b=180

80+b=180

b=100
