The perimeter of a triangle is 963 - 4ba+ 4a?. If two sides of a triangle are b-6a² and 11ba -- a², find the third side.
Answers
Answer:
As we know that the perimeter of a triangle is the sum of all the sides.
Suppose that the third side of the triangle is X then,
According to the given data in the question-
14a
2
+20a+13=3a
2
+5a+1+a
2
+10a−6+X
14a
2
+20a+13=4a
2
+15a−5+X
X=14a
2
+20a+13−(4a
2
+15a−5)
X=14a
2
+20a+13−4a
2
−15a+5
X=10a
2
+5a+18
Hence, the third side will be 10a
2
+5a+18.
