Answer:
k + a = 62
k = 31 + a
Step-by-step explanation:
Given that:
Sum of ken and Alan's age = 62
Ken is 31 years older than Alan
k + a = 62 - - - (1)
k = 31 + a - - - (2)
Hence, the system of equation which best describes the ages of Ken and Alan are:
k + a = 62
k = 31 + a
Answer:
70 degrees
Step-by-step explanation:
total angle in a triangle is 180 degrees
180-40= 140
Angle b and c is total of 140 degrees
they are isosceles so their measurements would be same.
angle b and c is 140÷ 2 = 70
so angle b is 70 degrees
