<span>Let ∠ ADC = 2β
Ac and BD are perpendicular bisectors of each other ⇒⇒ (Given information)
∴ BD </span><span>bisects the angle ADC
∴ ∠ADE = 0.5 ∠ADC = β
And in ΔADE:
∵∠DEA = 90° ⇒⇒⇒ from the given information
∴∠DAE = 90° - β
And AC bisects ∠DAB </span><span><span>⇒⇒⇒ from the given information
</span>∴∠EAB = ∠DAE = 90° - β</span>
Answer: vertical,corresponding,transitive property
Step-by-step explanation:
Box A : 8.25
Box B : 8.2
Box C : 8.225
Box D : 8.05
heaviest box is box A
Answer:
RS = 15 and RT = 18, then ST = 3! :D
Step-by-step explanation:r = 1 --> s=15 & t=18 so st = 270
r = 3 --> s = 5 & t = 6 so st = 30
r = 5 --> s = 3 & t = 3.6 so st = 10.8
etc
==============
In literal terms:
s = 15/r
t = 18/r
