Use this image to find the measure of angles 1, 2, and 3.

∠ 1 = ∠ 3 = 63° , ∠ 2 = 117°

Step-by-step explanation:

∠ 2 and 117° are vertically opposite angles and are congruent , then

∠ 2 = 117°

∠ 1 and 117° are adjacent angles on a straight line and sum to 180°

∠ 1 + 117° = 180° ( subtract 117° from both sides )

∠ 1 = 63°

∠ 1 and ∠ 3 are vertically opposite angles and are congruent , then

∠ 3 = 63°

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
