Answer:
Rate = 0.7%
Step-by-step explanation:
Rate = Interest / (principal x time)
rate = 12.83 / ((550) x 12/4)
rate = 12.83 / (550 x 3)
rate = 12.83 / 1650
rate = 0.007
rate = 0.7%
The tangent function is given by:
Since the angle is in the 3rd quadrant the opposite side and the adjacent side are negative. So, the cotangent function is given by:
Answer:
12/5
Answer:
Step-by-step explanation:
Sin x = opp/hyp
Sin x = 4/7
Sin x = 0.5714
X =sin-¹(0.5714)
X = 34.8
X = 35°
Answer:
178 - 3x.
Step-by-step explanation:
The three angles in a triangle add up to 180 degrees so an expression for the third angle is:
180 - (x + 9) - (2x - 7)
Distributing the negative over the parentheses, we have
180 - x - 9 - 2x + 7
= 180 - 9 + 7 - x - 2x
= 180 - 2 - 3x
= 178 - 3x (answer).
