Question

Find the value of a and b that would make the quadrilateral a parallelogran.​

Answer 1

Step-by-step explanation:

(4a-8)+(8a-10)=180°. ( adjecent angle sum )

12a-18=180°

12a=180+18

a=198/12

a=16.5

4a-8=4×16.5-8=66-8=58°

58°+5b+6=180°. (. ". ". " )

5b+64=180°

5b=180-64

b=116/5

b=23.2
