Answer:
115° and 245°
Step-by-step explanation:
Given
cos x = - 0.4226
Since cos x < 0 then x is an angle in the second / third quadrants, thus
x = (0.4226) = 65° ← related acute angle , thus
x = 180° - 65° = 115° ← angle in second quadrant
x = 180° + 65° = 245° ← angle in third quadrant
.85x=10.2
your answer is x = 12
m=6.50t
6.50 per ticket so you multiply 6.50 by t. The money collected is the answer to the equation. Hope this helps!
