Answer:
(x, y) =(-4,10)
Step-by-step explanation:
6x+2y=-4
3x+2y=8 /*(-1)
6x+2y=-4 (1)
-3x-2y=-8 (2)
6x+2x=-4
(1)+(2) 3x=-12
6x+2x=-4
x=-12/3
6x+2y=-4
x=-4
6*(-4)+2y=-4
x=-4
-24+2y=-4
x=-4
2y=-4+24
x=-4
2y=20 y=20/2 y=10
(x,y)=(-4,10)
Answer:
Draw a perpendicular line from point A to line segment BC. Name the intersection of said line at BC “E.” You now have a right angled triangle AED.
Now, you know AD = 6 m. Next, given that the trapezoid is a normal one, you know that the midpoints of AB and DC coincide. Therefore, you can find the length of DE like so, DE = (20–14)/2 = 3 m.
Next, we will use the cosign trigonometric function. We know, cos() = adjacent / hypotenuse. Hence, cosx = 3/6 = 1/2. Looking it up on a trigonometric table we know, cos(60 degrees) = 1/2. Therefore, x = 60 degrees.
Alternatively, you could simply use the Theorem for normal trapezoids that states that the base angles will be 60 degrees. Hope this helps!
