<u>Answer-</u>
<em>The height of the traffic light is 21.8 feet.</em>
<u>Solution-</u>
As shown in figure, we can see the right triangle formed from the situation,
From the question,
BC = the distance walked by Andrew from the traffic light = 20 feet
Height of Andrew's eye = 5 feet
Height of the traffic light = AB + Height of Andrew's eye
From the properties of triangle,
Therefore, height of the traffic light = AB + Height of Andrew's eye = 16.8+5 = 21.8 feet

notice, we didn't use the negative value, valid though as it is, because in this case "a" can't be negative.
So Denver scored 3/4 as many as Dallas so:
3/4 x 26 3/5
If we make 26 3/5 an improper fraction it becomes
133/5
133/5 x 3/4 =
(133 x 3)/(5x4)=
399/20 average points
Which as a mixed fraction is:
19 19/20
Can I get brainliest answer.
1863lb/64bags=29.109375 lbs/bag or if you prefer
29lb 1.75oz per bag
...
1863lb(bag/64lb)=29.109375 so he will need 30 bags so that the remainder can be bagged.
