Answer:

BC = 19.78

Step-by-step explanation:

using sin(x) rule

sin(54)= 16/BC

sin(54)=0.80

∴0.80=16/BC  (divied both side by 0.80)

BC=16/0.80 =19.78

Solve for 43.<br> 43 = [?]<br> 58°<br> 139° 41°<br> 43
Dovator [93]

Answer:

∠3 = 81

Step-by-step explanation:

Interior angles in a triangle add up to equal 180°

Hence, 58° + 41° + ∠3 = 180

58 + 41 = 99

99 + ∠3 = 180

* subtract 99 from each side *

99 - 99 cancels out

180 - 99 = 81

we're left with ∠3 = 81°

A "principal square root" is always...
vladimir1956 [14]

Really none of the above.  

A principal square root of a real number is a positive real number (or a positive real number times i, if you're up to complex numbers, but let's assume not.)  It's not necessarily a positive integer, √2 being the obvious example.

Is √2 a positive fraction?   We can write it as √2 / 1 so I suppose it is.  It's certainly not a rational number.  Even if we grant irrationals as fractions surely √0=0 isn't a positive fraction.  So "always" isn't correct.

I'd go with none of the above, but if I had to choose I'd choose D.
