Question

Can anyone help with this one question im giving 100 points plz dont answer if you dont know.

Answer 1

Answer:

Solution given:

<C=90°

<B=48.7°

a=?

<A=?

b=?

Now

In right angled triangle

<A+<B+<C=180°[Sum of interior angle of a triangle is 180°]

<A+48.7+90=180°

<A=180-90-48.7

<A=41.3°

again

Sin 48.7=perpendicular/hypotenuse=b/c

b=sin 48.7°×16

b=12

again

Cos 48.7°=base/hypotenuse=a/c

a=Cos 48.7°×c

a=Cos 48.7°×16

a=10.6

So ,answer is:D.m<A=41.3°,a=10.6 and b=12.
