Ok I don't understand how to find similar figures when using proportions. Can someone explain it to me? Two figures that have the same shape are said to be similar. When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if ...

Given: in triangle ABC, angle B= 120 degrees Prove: angle A does not= 60 degrees Plan: use indirect proof Assume temporarily that Measure angle A = 60. Then measure angle C=60, and measure angles A+B+C=180= 60+B+60=180. Therefore the temporary assumption that measure angle A=...

pls help w/t math ?
in a right triangle ABC, if ab is 14 and bc is 12 wut is bd? there is a pic of a large trangle abc and in it is a line drawn down angle c making it line cd. angle acd then becomes a right trangle as well. i tried working = proportions and pyth thm but i dont seem to be getting...

Fe(NO3)3 + SCN^- ==> FeSCN^+2 mols Fe(NO3)3 = M x L mols SCN^- = M x L. Obviously, SCN^- is the limiting reagent. (SCN^-) = mols/L total solution OR, if my arithmetic is ok, (FeSCN^+2) = 0.0002. Check me out on that. Then A = abc. You know A = 0.550 for the standard. You ...

I assume you drew it. Now angle ABC = angle EDC (both right angles) and Angle ACB = angle ECD (opposite angles) By the way that means angle BAC=angleDEC because they are complementary to equal angles Therefore I claim the triangle CDE is similar to triangle CBA Therefore AB/BC...

math- Triangle facts
(1) A triangle is called an isosceles triangle if it has two sides with equal lengths. Consider an isosceles triangle ABC with AC = CB. Then side AB (i.e. the side that is not equal to the other sides) is called the base side. The angle opposite the base side is called the ...

Use Beer's Law to determine the constant a in A = abc. You know concn, you know b, the cell length (but it is the same, I assume for both so actually you need not include that), and you know A. Calculate the constant a. Then on the trial, you know A, you have found a, ...
