Since it is shown that 2 of the sides of the triangle are congruent, we can assume that they have the same angle measures.
so to solve for the missing angle you can set up an equation equal to 180 since all triangles add up to 180 degrees.
21 + 21 + x = 180
42 + x = 180
x = 138
the value of the missing angle should be 138 degrees

Answer: (x + [-1], y + [1])
Step-by-step explanation:
       <em>See attached. </em>We can draw, or picture it in our heads, what the reflection would look like. Then we can pick one (or multiple to test) points and see the translation.
       We can also test with a set of points. B', (2, 4) becomes G in the transformation. G is at (1, 5)
       (1 - 2, 5 - 4) -> (-1, 1)

C) 3 ounces
4 × 5 3/4 = 23 
the total weight of the snack mix before the cheese puffs were added was 20 ounces. so 23 - 20 = 3 ounces.
