It could be 7:4 or, 28:16.
1:1
Your best option to solving these types of problems is to visualize aka sketch it out. So you draw two parallel lines, line PQ and line RS. It is also given that PR and QS are perpendicular to PQ and RS. By now you, you have a rectangle. Why is it a rectangle? A rectangle is a quadrilateral that has four right angles. The four sides are PQ, QS, SR, and PR and the four right angles are formed from the fact that the lines are perpendicular. Knowing that the figure described is a rectangle, we can also deduce that it is a parallelogram. A parallelogram, by definition, has equal opposite sides. That means that PQ has to equal RS in length, and PR has to equal QS in length. This means that the ratio is 1:1.
Hope this helps!
(Note, this does not actually mean each side is 1 in. or 1 cm. Since the sides are equal the ratio will always be simplified down to 1:1. For instance, x:x always simplifies to 1:1 because we divide x from both sides.)
Answer:
figure 2
Step-by-step explanation:
Make a proportion of corresponding sides
Side AU corresponds to Side AB
Side UV corresponds to Side BC
Find AB by adding AU and UB
AU = 20x + 108
UB = 273
AB = 20x + 381
Make proportion
AU/AB = UV/BC
20x + 108/ 20x + 381 = 444/ 703
Cross Multiply
(20x + 108)(703) = (20x + 381)(444)
14,060x + 75,924 = 8,880x + 169,164
Solve for x
14,060x + 75,924 = 8,880x + 169,164
I'm sure you can figure this out
