Triangle and Line## Would y also be equal to 90 +

## That works too! We get...

That works too! We get...

Quantity A: 7x and Quantity B: 90 + 5x

Subtract 5x from both to get: Quantity A: 2x and Quantity B: 90

At this point, we have a similar situation as in the solution.

## A: 7x

B: 180-2x

add 2x both quantities

A: 9x

B: 180

if x=20 then both will be equal, but thats not possible since sum of angles of triangle will be greater than 180. hence x will be lesser than 20, in total 9x will be lesser than 180.

B answer.

## Excellent reasoning!

Excellent reasoning!

## We can even substitute value

Column A : 90

Column B : 90+5x

so column B > A

## Very nice!

Very nice!
