Answer:
The second one is correct.
Well first of all, 'kg' means mass, not weight.
If the total mass of all his baggage is 35 kg, and the mass
of his backpack is 4 kg, then the combined mass of all of his
checked bags is (35 - 4) = 31 kg.
If all of his checked bags have the same mass, then the mass
of each one is
(31 kg / 222 bags) = 139.64 grams/bag (rounded)
Hello!
To do this, we know the two triangles are similar, so we can set up a proportion, and then find the length of the lake.
----
The two triangles (Triangle AEB and ADC) are similar. We know this because all the angles have the same measurement - They all share angle A, they both have a right angle, and therefore, their third angle measures the same.
What we know about both triangles is their hypotenuse length. We know that triangle AEB has a hypotenuse that measures 320 m, and ADC has a hypotenuse that measures 320 + 162, or 482 m.
320 : 482 is therefore the ratio between the side lengths of two triangles (AEB : ADC). We can simplify this to 160 : 241.
Now, what we are looking for is the side length DC. The corresponding side to this in triangle AEB is EB, and we know it measures 40 m. Therefore, using the ratio, we can find the measure of DC.
160 / 4 : 241 / 4
40 : 60.25
Therefore, the measure of DC is 60.25 m.
