Question

plz plz plz answer both properly.no working needed

Answer 1

1. For parallelogram:-

Sum of all angles of parallelogram = 360°

$3x - 15 + 2x + 2x + 2x + 24 = 360 \\ \\ 9x + 9 = 360 \\ \\ 9x = 360 - 9 \\ \\ 9x = 351 \\ \\ x = \frac{351}{9} \\ \\ x = 39$

2. For triangle :-

Since it is isosceles triangle:-

$3x - 5 = 19 - x \\ \\ 3x + x = 19 + 5 \\ \\ 4x = 24 \\ \\ x = \frac{24}{4} \\ \\ x = 6$

Perimeter = Sum of all side

$= 3x - 5 + 19 - x + 2x \\ \\ = 4x + 14 \\ \\ = 4(6) + 14 \\ \\ = 24 + 14 \\ \\ = 38$

Hope it helps.
