The ratios 84/105 and 128/160 are proportional
<u>Solution:</u>
Given, two ratios are
and 
We have to give two different reasons to support the answer.
<em><u>Reason 1:</u></em>
Now, we know that, numerators and denominators should be proportional to be two fractions in proportion.

So numerators and denominators are in proportion, then given two fractions are proportion.
<em><u>Reason 2:</u></em>
Now, values of two fractions must be equal:

So, values of two fractions are equal, then they are in proportion.
Hence, the given two fractions are in proportion.
We have been given that in ΔHIJ, the measure of ∠J=90°, the measure of ∠I=29°, and JH = 88 feet. We are asked to find the length of IJ to the nearest tenth of a foot.
First of all, we will draw a right triangle using our given information as shown in the attachment.
We can see that in triangle HIJ, the side IJ is adjacent side to angle I and JH is opposite side to angle I.
We know that tangent relates opposite side of right triangle to adjacent side.





Upon rounding to nearest tenth, we will get:

Therefore, the length of the side IJ is approximately 258.8 units.
