What are the terms in the expression 2x -4y + 8 a) 8 b) 2x 4yand 8 c) 2x and 4y d) 2 4 and 8

b) 2x 4yand 8

Step-by-step explanation:

the terms in the expression are the things separated by plus and minus

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

the answer to this question is yes
