A biologist was observing a pack of wolves. There were 8 female wolves and the ratio of female wolves to male wolves was 4:5. A little later some more male wolves arrived and the ratio was now 1:2. How many more male wolves arrived? more male wolves arrived.​

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

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

do your own work and don"t cheat.
