The unknown angle is 90 degrees
Answer:
x= 256.8(rounded)
Step-by-step explanation:
For this problem, use tangent because you have adjacent and are trying to find the opposite side from the angle. Tan(15°)= x/300 so x=300tan(15°)
It was negative, but you probably take absolute value.
Answer:
289/4
Step-by-step explanation:
x² + 17x + 12 = 0
x² + 17x = -12
Take half of the second coefficient, square it, then add the result to both sides.
(17/2)² = 289/4
x² + 17x + 289/4 = -12 + 289/4
(x + 17/2)² = 241/4
Y=50x+550
This is a linear equation of the form:
y=mx+b, where m=rate of change or slope and b=y-intercept.
The slope is the rate of change and the y-intercept is the value of y when x=0, which is the initial value. So in this context...
The change per week is $50.
The starting amount was $550
