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: A
I'd have to say a because it's the closest answer or best estimate.
y = -3.75
1 - 0.5 = 2(y+4)
0.5 = 2(y+4)
0.5 = 2(0.25)
0.25 - 4 = -3.75 = y
