9. Order the angles of the triangle from smallest to largest

It is b. ACB

Step-by-step explanation:

If draw a triangle, you would give the longest side to BC, because their angles equal 10

And you would give AC the shortest side of the triagle because their angles equal 7

And AB the last side because it is in between the other sides

Since AC have the smallest angle, they would have the smaller numbers

then that leaves B as the biggist number
