Because the two angles on the right add to 180 degrees, we can create this system:
We can also prove that
, which, when solved, shows that
.
When plugged in to the original equation, we find that y = 105 degrees.
Answer:
- 19/12 or - 1 7/12
Step-by-step explanation:
11/12 + ( - 8/12) = - 19/12 = - 1 7/12
Change the denominator for 12, and leave 11/12 alone, but multiply 4 to the numerator of - 2/3.
Answer:
Step-by-step explanation:
The answer is 4/3, you just need to plug and solve.
