Answer:
65 degrees
Step-by-step explanation:
The degrees always has to add up to 180 degrees, so if you add 90 degrees and 25 degrees, you get 115 degrees. So since it has to be 180 degrees, you add 65 to 115, and you get 180 degrees.
-69=7v-6. Add 6 to both sides
-75=7v. Divide 7 to both sides
-75/7=v
Answer V= -75/7
