6x + 4y = -24
30x + 20y = -120
You can multiply all of the numbers by any common factor and get an equation that works.
Answer:
74°
Step-by-step explanation:
Let ½(theta) = X
Tan(X) = opposite/adjacent
= 7.5/10
X = (tan^-1)(0.75)
X = 36.8698976458
Theta = 2X = 2(36.8698976458)
Theta = 73.7397952916
Nearest degree: 74°
