The 2 lines intersect, and by definition it will create equal opposite angles. Since we know that the angle created is 125 degrees, then the angle on the opposite side also must equal 125 degrees. But wait, they broke up the angle into 2 angles made up of a 64 degree angle and an X degree angle. These 2 angles must add up to 125 degrees.
x + 64 = 125
x = 125 - 64
x = 61 degrees
<span>Semicircle area = circle area / 2 = (pi*r^2)/2
16 in is the radius. Let's call the area of this semicircle s.
3.14*16^2=s
</span><span>Trapezoid area = ((base 1 + base 2) / 2) * h
Here, base 1 is 44 and base 2 is 36. The height (h) is 20. Let's call this trapezoid's area t.
(44+36)/2 *20 = t
</span>
<span>We can remove the area of the semicircle (that created by the windshield wiper) by subtracting it from the area of the trapezoid.
t - s = uncleaned area
[(44+36)/2 * 20] - [3.14 * 16^2] = uncleaned area</span>
Answer:
Not rlly sure, might be x=4/5y??? i dont know
Step-by-step explanation:
14÷2=7
18÷2=9
for the first equation
14/y=7
cross multiply will be
7y=14
divide both sides by the co efficient of y which is 7
y=14÷2
y=2
same step for the second equation
Divide by 2. 10/2 divided by 2 = 5/1
