The simplest form of 145/261 is 5/9
[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.
-> The question marks are because the letters are too blurry to read.
Answer:
Step-by-step explanation:
f+t=40 and 4f+2t=100
4f+2t=120
4f+2t=100
2t=20
t=10
So f=20
0.4 divided by 0.242 = 0.605 then you can either multiply. 0.4 times 0.605 and get 0.242 or you can do 0.242 times 0.605 and get 0.4 either way will work
