Answer: Always true.
Step-by-step explanation:
When two angles are added up to 180°, then the pair of angles is called as supplementary angles.
Since, the measure of right angles = 
Therefore, the sum of two right angles will be :_

Therefore, The angles are supplementary angles.
Hence, The statement "If two angles are right angles they must be supplementary" is always true.
To answer this item, we let x be the time for the faster plane and h be the distance traveled which is the same for both planes. Distance is calculated by multiplying speed and time. Thus,
(558)(x) = (496)(x + 0.5)
The value of x from the equation is 4.
Time spent babysitting by Lucy = Tl = 4 hours
Time spent babysitting by Maria = Tm = x * 4 hours
Now we need to determine for what values of x is Tm > Tl
⇒ x * 4 > 4
⇒ x > 1
So for x > 1, Mary spends more time babysitting than Lucy does
Answer:
4in
Step-by-step explanation:
So the area is base times height. We have the area, which is 24, and we have the height, which is 6. So we do, 24/6=4.
