Question

What is the value of y?

Answer 1

Answer:

y = 22°

Step-by-step explanation:

the sum of the interior angles of a triangle is 180 degrees

40 + 2x = 180

2x = 140

x = 70

'x' and '5y' form a linear pair, meaning they add up to 180 degrees

x + 5y = 180

substitute 70 for 'x'

70 + 5y = 180

5y = 110

y = 22
