Answer:

n = 144

Step-by-step explanation:

6 / n = 5/120

6 * 120 = 5*n

5n = 6*120

5n = 720

n = 720/5

n = 144

Answer:

144

Step-by-step explanation:

you should use a proportion to do this to make it easier to solve.

$\frac{6}{n} = \frac{5}{120}$

cross multiply the numbers

$5n = 6*120$

$5n = 720$

then divide 720 by 5

$n = 144$

Given the same triangle from part C, if line segment AB measures 12 inches and line segment BC measures 5 inches what is the mea

exis [7]

Answer:

4.615 in

Step-by-step explanation:

Triangle ABC and ABD are similar because they have two corresponding congruent triangles that is right angle and ∠A. Triangle ABC and BCD are similar because they have two corresponding congruent triangles that is right angle and ∠C. Therefore Triangle ABC, ABD and BCD are similar. Since they are similar, then their sides are proportional in length.

In triangle ABC, using Pythagoras theorem:

AC² = AB² + BC²

AC² = 12² + 5²

AC² = 144 + 25 = 169

AC² = 169

AC = √169 = 13 in

Using similar triangle for ΔABC and ΔABD:

$\frac{AC}{AB}= \frac{BC}{BD} \\\\\frac{13}{12}=\frac{5}{BD}\\\\BD=\frac{12*5}{13}\\ BD=4.615\ in$
