What is the value of the expression
x - 11 when x = 46?

The answer is 35.

46-11=35

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

question:

could we have options?
