Hello,

I suppose as we don't see correctely the 2nd image, that it is the first one.

Angles DOY and DKY intersept then same arc are equals.

5x+15=3x+21
==>2x=6
==>x=3 and 5x+15=5*3+15=30°, 3x+21=3*3+21=30°
Angle OYK=15x=15*3=45°
Angle ODK=9x+18=9*3+18=45° =Angle OYK which intersept the same arc.

Factor the expression 54x+81 using the GCF.

Vikki [24]

We are given the expression,

54x+81

Here we have to find Greatest Common Factor of 54 and 81

Factors of 54 are 1, 2, 3, 6, 9, 18 and 27.

Factors of 81 are 1, 3, 9, 27 and 81.

Greatest common factor of 54 and 81 is 27.

So we take out 27 common, rewriting the expression

27(2x+3)

Answer: 54x+81 in factored form equals 27(2x+3).

Which equation shows that the Pythagorean identity is true for ø = 270º?

viktelen [127]

Answer: (a)

Step-by-step explanation:

Given

angle is $270^{\circ}$

Sine and cosine at this angle is

$\Rightarrow \sin 270^{\circ}=-1\\\Rightarrow \cos 270^{\circ}=0$

Put the values in the identity $\sin ^2\phi +\cos^2 \phi=1$

$\Rightarrow (-1)^2+(0)^2=1$

The same thing is depicted by option (a)
