Answer:
34.78 feet
Step-by-step explanation:
1) using the cosine function, I did cos(43)=x/51
This is because cosine is equal to adjacent over hypotnuse
Once I found x, I used the pythagorean theorem to get 34.78 feet
Answer:
60
Step-by-step explanation:
<C+<D = 180 since they form a straight line
5x+20 +3x = 180
8x+20 = 180
Subtract 20 from each side
8x+20-20 = 180-20
8x = 160
Divide by 8
8x/8 = 160/8
x = 20
We want to find angle D
<D = 3x= 3*20 = 60
Answer:
#2: y-intercept=-2
Bottom left graph: Slope:4/2
y-intercept:-2
Equation: y=4/2x-2
Bottom right graph: Slope:-2
y-intercept:8
Equation: y=-2x+8
49,000 is the nearest round to the hundredth to 48,950
Answer:
A common mistake is doing x2-x1/y2-y1 instead of the correct slope formula which is y2-y1/x2-x1
