Simplify the following expression: 3j 5k 2+63 42k + 6
None of these
3j - 3k - 4
O9j - 3k + 4
O9j - 3k - 4
0 9j + 3k + 4

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
