Answer:
The lengths of all sides of the triangle will be 21 cm, 21 cm, and 21 cm
Step-by-step explanation:
Given that the perimeter of the triangle = 63 cm
And the length of one side = 21 cm
and one of the medians is perpendicular to one of its angle bisectors
Since triangle has 3 sides,
Median = 63 ÷ 3 = 21
Therefore each side length = 21 cm
Answer:
r = 
Step-by-step explanation:
Express the equation with the term in r on the left side
P + Prt = A ( subtract P from both sides )
Prt = A - P ( isolate r by dividing both sides by Pt )
r =
