Question

Solve for the value of V: (9v+6)° (7v+4)°

Answer 1

We have a right angle between the other two angles. The sum of all these angles must be 180. Then, we have:

`9v+6+90+7v+4=180`

Then, adding like terms, we have:

`9v+7v+6+90+4=180\Rightarrow16v+100=180\Rightarrow16v=180-100`

Then, we finally have:

`16v=80\Rightarrow v=(80)/(16)\Rightarrow v=5`

Then, the values for v is 5.
