Parallelograms have adjacent angles supplementary (sum to 180).
For pair r and s,
3x+120=180, => x=(180-120)/3=20 °
Similarly, for pair q and r,
2y+120=180 => y=(180-120)/2 = 30 °
Answer:
64.025°F
I think I did it right
Step-by-step explanation:
65=100%
65/100=0.65
0.65=1%
3%=1.95
4.5%=2.925
65+1.95=66.95
66.95-2.925=64.025

[8] The hypotenuses must be congruent, DE and IJ
HL is hypotenuse-leg, or where the hypotenuse and one leg are congruent.
Since we see a leg is congruent, to prove they are congruent with HL we will need to know that the hypotenuses are congruent.
[9] Another leg, AC and YX
LL is leg-leg. Since we have one leg, we will need the other leg to prove the triangles are congruent by LL.
[10] A leg, DE and E? or FE and E?
LA means leg-angle. The angles by point E are vertical angles, so they will be congruent. To finish prooving the congruence using LA we will also need a leg.
