Answer:

0.9212 (Answer b)

Step-by-step explanation:

Note that sin 52 deg 47 min = sin (52 47/60 deg)

Using the fact that pi radians = 180 degrees, convert the argument of the sine function to radians:

sin ( [52 47/60][pi rad][180 deg] )

= sin ( 0.2932 pi) = 0.9212

Using a calculator to evaluate this, we get 0.2891

Can someone help me please please please

Use the Pythagorean theorem $a^{2} + b^{2} = c^{2}$ to find the missing side length of a right triangle

In this case, after you plug in the given numbers your equation is $12^{2} + y^{2} = 20^{2}$

Then, Just solve that equation for y.

$144 + y^{2} = 400$

$x^{2} = 256$

$\sqrt{} y^{2} = \sqrt{256}$

y = 16

So the answer is B, 16 cm.

I hope this helps, please feel free to ask questions if you're still confused :)

If there aren’t any degrees and it doesn’t state that the triangle is equilateral then you cannot solve this equation without more information
