Answer:
For problem 17a) your answer is: x=11.5 degrees
Step-by-step explanation:
1. Measure of angle BCA will be 180°-124°=46°
2. In triangle BCA, you now have two angles. 46 degrees, and 2x.
3. Measure of angle ABE is an exterior angle of triangle BCA
4. Using the exterior angle theorem, angle ABE=angle BCA+angle BAC
5. substitute!! 2x+46=6x
6. move 2x over and then divide by 4, you get x=11.5°
7. You can plug the answer back in to check if it correct!! have a nice day :>
Answer:
Step-by-step explanation:
First, find the slope of the given line by finding two points. (0, 3) and (1, 1)
Use the equation for slope rise/run to find the slope.
From the left point to the right point, it goes down 2 units and to the right by 1 unit
-2/1 = -2 = slope
We already know the y-intercept which is y = 3, when x=0 and when the line crosses the y-axis
y=-2x+3 is the equation of the line.
Perpendicular line's slope is the opposite reciprocal of the original line's slope. Opposite reciprocal of -2 would be 1/2
y = 1/2(x)
y=1/2x -5/2
$310 dollars because after it res and decreased it gained $.10 and 100 x 3 is 300 so thats before you calculate how much it rose so .10 x 100 is 10 so add that to 300 and you get 310
50 Dollars For The Member-Ship
2 Dollars For The Class (C)
Y=Total (unknown because you dont know how may classes)
Y=50(C)
