Question

The perimeter of a triangle is 8+13a+7a2 and two of its sides are 2a2+3a+2 and 3a2-4a-1 . Find the third side

Answer 1

Answer:

Step-by-step explanation:

Answer. Y=3a^2-4a-1 Z=? Hence , the third side of triangle =2a^2+14a+7

Answer 2

Step-by-step explanation:

Sum of three sides of triangle= Perimeter of Triangle

Let third side be x

(2a2+3a+2) + (3a2–4a–1) + x = 8+13a+7a2

2a2+3a2–1+1+x =8+13a+7a2

x= 8+13a+7a2–2a2+3a2–1+1

x = 8+13a+8a2
