Question

please answer this question and I will follow you if it is correct ​

Answer 1

Step-by-step explanation:

ans c

let a be the no which should be add

so a+x²-y²+2xy= x²+y²+5xy

so a= x²-x²+y²+y²+5xy-2xy

a= 2y²+3xy

let x be the angle

so ATQ

3x-20=180

3x= 200

x= 200/3=66.66

sorry didn't know the b part

Answer 2

Answer:

Step-by-step explanation:

5a)

let the angle be x° and 3x°-20

3x-20°+x°=180

4x°-20=180

x=50°

therefore the angles are 50° and 130°

b) let no of men and women be 5x and 8x respectively

8x=56

x=7

i)35 men

ii)56 women

c)x²+y²+5xy-(x²-y²+2xy)

=x²-x²+y²+y²+5xy-2xy

=2y²+3xy
