Question

In the given isosceles triangle, find the value of 'y' if its perimeter is 49 cm.​

Answer 1

8cm

Step-by-step explanation:

We have to equal sides whose length is 2y+3

We have been provided with the perimeter i.e. 49 cm

So lets find value of y

(2y + 3) + (2y + 3) + (y + 3) = 49

5y + 9 = 49

y = 40 / 5

y = 8 cm

...good luck with your studies

I solved for the value of x ..in case you needed to know how to find x here .

Lets find the value of x and other angles .

Since it is isosceles, the 3rd angle will be (2x + 30)°

Sum of all interior angles of a triangle = 180°

x° + (2x + 30)° + (2x + 30)° = 180°

5x° + 60° = 180°

x° = 120°/5 = 24°

Answer 2

Answer:

8

Step-by-step explanation:

2y+3+2y+3+y+3=49

5y+9=49

5y=49-9

y=40/5

y=8
