2. Isaac measured the length of a pen to be 25 cm. The actual length of the pen is 30 cm. Which of these is closest to the percent error for Diego's measurement? A. 20%
B. 120%
C. 16.7%
D. 16.6%

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

c. side angle side. u shares the same sides

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

hi there, i would be interested to you with your test, may you add the questions and answer options.
