Option - ∠ 3 and ∠ 7 is correct.
Step-by-step explanation:
∠ 3 and ∠ 7 are corresponding angles because
- Both lie below the parallel lines.
- Both lie in one side .
Y=7-4X
GRADIENT OR SLOP NEED TO BE SAME TO BE PARALLEL.
THE FIRST LINE WHEN X=0 Y IS 9 FROM EQUATION WHEN YOU PUT X=0 Y WILL BE 9
THE SECOND LINE WHEN X=0 Y IS 7 PASSES THROUGH (0,7)

Answer:
a) dm/dt = 0.2m
b) ln(m) = 0.2t + A
c) ln(m) = 0.2t + ln(20) - 0.6
d) 11 grams
Step-by-step explanation:
a) dm/dt = 0.2m
b) dm/m = 0.2dt
ln(m) = 0.2t + A
c) At t = 3, dm/dt = 4
dm/dt = 0.2m
4 = 0.2m
m = 4/0.2 = 20
So, when t = 3, m = 20
ln(20) =0.2(3) + A
A = ln(20) - 0.6
ln(m) = 0.2t + ln(20) - 0.6
d) find m when t=0
ln(m) = 0.2(0) + ln(20) - 0.6
ln(m) = ln(20) - 0.6
ln(m) = 2.3957322736
m = e^2.3957322736
m = 10.9762327224
m = 11
The length of longer base is 41 feet
<em><u>Solution:</u></em>
<em><u>The area of trapezoid is given as:</u></em>

Where , "a" and "b" is the length of base and "h" is the height
The length of one base of a trapezoid is 19 less than five times the length of the other base
a = 19 less than fives times b
a = 5b - 19
Height of 18 feet and an area of 477 ft squared
h = 18 feet
area = 477 square feet
<em><u>Substitute the values in above formula</u></em>

Therefore,
a = 5b - 19 = 5(12) - 19 = 41
Thus length of longer base is 41 feet
