Can anyone help with this one question im giving 100 points plz dont answer if you dont know. In each problem angle c is a right angle. Solve each triangle rounding answers to the nearest tenth show all work.

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.

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
