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.
The answer to this is 0.857142857143 i hope this helped you my guy.
193/990 Would be the answer. If you want the steps to find it, just ask.

Simply, 1250 feet of lawn will make supplies for:
= 1250/ 625
= 2
2 multicellular organism.
Answer:
x=−3/4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
435=−4x+285
Step 2: Flip the equation.
−4x+285=435
Step 3: Subtract 28/5 from both sides.
−4x+285−285=435−285
−4x=3
Step 4: Divide both sides by -4.
−4x−4=3−4
x=−34
