Question

FIRST person to answer gets brainliest plz help me

Answer 1

Answer:

since it is isosceles triangle.

3x-5 = 19-x

4x = 19+5

4x = 24

x = 6.

3x - 5

3(6) - 5

18-5

13cm

19-x

19 - 6

13cm

2x

2(6)

12cm

Perimeter of the triangle = Sum of all sides.

= 13 + 13 + 12

= 38cm.

Hope it helps you

Answer 2

Answer:

Since the two angles are equal ( isosceles triangle ), 3x-5 and 19-x are equal....

3x-5 = 19-x

3x+x = 19+5

4x = 24

x=6

1st side= 3x-5 = 3*6-5 = 18-5= 13 cm

2nd side= 19-x= 19-6 = 13 cm

3rd side= 2x = 2*6 = 12 cm

PERIMETER= 13cm+13cm+12cm= 38 cm
