it´s due in a HOUR (answer these questions but also can you show me how you do it to :> thanks) -Evaluate 1/2b + 1/6 when b=1/3

Step-by-step explanation:

() +           x =           + =           =

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

answ9x x 3=
