Given:
Area and altitude PS of ∆PQR are ar(∆PQR) = 180cm² and PS = 15.
To find:
The measure of side QR.
Solution:
According to the given information, PS is an altitude of ∆PQR. It means QR is the base of ∆PQR.
We know that, the area of a triangle is
Substituting the given values, we get
Divide both sides by 15.
Therefore, the measure of side QR is 24 cm.
I'm assuming you're looking for the measure of angle y. Rule is that angle y will be equal to 1/2 of its intercepted arc. That arc measures 360-160-60 which is 140. Half of 140 is 70. So the first choice above is the one you want.
It would take greater than 31.25 hours for Tim's price to be better. So in terms of whole hours it would take at least 32 hours of work for Tim's price to be better.
At least 50 Feet or Taller. Depending on the distance between each Floor.
