BeefHunger101

Step-by-step explanation:

Since opposite angles of a parallelogram are congruent, we have:

[tex]a=2b+17/5[/tex]

Also, since adjacent angles of a parallelogram are supplementary, we have:

[tex]7a+26b=176\[/tex]

Substituting into the above equation, we get:

[tex]b=3.805, a=11.01[/tex]
