Answer:
= r
Step-by-step explanation:
First write down the equation they gave you:
l = Prt
You need to ask yourself what is being done to r. r in this case is being multiplied by two variable: P and t. To undo multiplication you divide, the set up for division:
I divided by the two numbers, so it would be easier. The P and T cancels out on the right and you are left with r. On the left, however, it stays the same because there are no like terms to solve with. You just leave as it is.
The result you get is:
2 angles are less than a right angle.
Is states that sum of all interior angles of any polygon is fixed which is given by formula : (n-2)*180 degree.
Sum of all the three angles of a triangle is ( n-2 ) *180degree = (3-2)*180 degree = 180 degree.
since one angle is 90 degree, any other angle can't be of 90 degree or more otherwise it won't satisfy condition of sum of interior angles.
