Please help me in this question!

Answer 1

Answer:

102,102,78,78

Step-by-step explanation:

3x - 15 + 2x + 2x + 2x + 24= 360 (sum of angles of parallelogram)

9x + 9 = 360

9x = 360 - 9

9x = 351

x = 351 ÷ 9

x = 39

Angles

3(39)-15 = 102

2(39) = 78

2(39) = 78

2(39) + 24 = 102

Answer 2

3x-15, 2x,2x,2x+24 this is quadrilateral
we know that 4 side sum is 360 therefore 3x-15 + 2x + 2x + 2x+24= 360
9x+9=360
9x =360-9
9x=351
x=351/9
x=39
after that we outing the value of x in given equation
after that :- 3x-15= 3*39-15 = 102
similarly 2x =2*39=78
2x =2*39=78
2x+24=2*39+24=102

after that we check our answer
how' :- 102+78+78+102 =360
hence proved
