Answer 1

Answer:

opposite angle oh parallelogram are parallel

Answer 2

Step-by-step explanation:

1) 3x-10=x+80 { opposite angle of parallelogram is equal}

3x-x=80+10

2x=90

x=45

3) to find- Angle A

angle A= 3x-10

" " " " ". = 3(45)-10

" " " " " "= 135-10

angle A= 125

5) angle C= x+80

angle C= 45+80

angle C= 125

2) 3x-10= y+25

3(45)-10= y+25

125-25= y

100= y

4) angleD = y+25

angleD= 100+25

anlgeD = 125

6) angleB = angle D { opposite angle are equal}

angle B = 125

8) equal to each other

9) equal

10) equal
