Answer:
I hope this makes sense, sorry for the lack of proofs.
Step-by-step explanation:
It is given that S is the midpoint of line QT. The definition of a midpoint is that it bisects the line it is on. So, line QS and line TS are congruent, or the same.
Now, we also know that line QR and line TU are parallel. Because they are parallel, it means that they form congruent corners with lines QS and TS..I think the proof here is "angles opposite to congruent sides are congruent in a triangle." But I'm not sure if this is right. Anyways, this means angles RQS and UTS are congruent.
There's also some proof that when two lines cross, the opposite angles are congruent. This means that angles TSU and QSR are congruent.
Therefore, by ASA (angle-side-angle) ΔQRS ≅ ΔTUS.
2x+50 and 7x are "vertical angles" and are thus equal to one another.
2x+50 = 7x
50 = 5x
x=10 (answer) You should find the actual angles.
They are 2(10)+50 = 70 and
7(10) = 70
Answer:
Step-by-step explanation:
If it was like....
then you subtract 5 minus 3 to be left with a^2 on the numerator
That would be how you would take it away.
Distribute 6x into (x - 2y):
= 6x^2 - 12xy
Hope this helps.
Answer:
You need 3.195 pints of blueberries. I would recommend simplifying this number to 3.2.
Step-by-step explanation:
Multiply the number of needed liters by 2.13 to convert the units from liters to pints.
