In ABC, a = 13,b=21, and c = 27. Find mA.

coldgirl [10]

Answer:

Step-by-step explanation:

a = 13 ; b = 21 ; c = 27

S = (a + b + c)/2

$= \dfrac{13+21+27}{2}\\\\=\dfrac{61}{2}\\\\= 30.5$

s- a = 30.5 - 13 = 17.5

s - b = 30.5 - 21 = 9.5

s -c = 30.5 - 27 = 3.5

Area = $\sqrt{s(s-a)(s-b)(s-c)}$

$= \sqrt{30.5*17.5*9.5*3.5}\\\\=\sqrt{17747.1875} \\\\=133.21\\\\=133$

$\dfrac{cbSin \ A}{2}=133\\\\\dfrac{27*21*Sin A}{2}=133\\\\Sin \ A = \dfrac{133*2}{27*21}\\\\Sin \ A = 0.4691\\\\A = Sin^{-1} \ 0.4691\\\\\\$

A = 27°

Basically, you could set these proportions up in two ways. You could set it up as 5/35=10/x, or you could set it up as 5/10=35/x. Either way, you will get the same answer. After setting one of them up, cross multiply. You should come out with 5x=350. Divide 350/5. Here you should get the answer of 70. 70 should be the length of LN
