No because the first nine means 9,000,000 (nine million)and the last nine means just 9 meaning the first"nine's" value is a lot greater

Answer:

\boxed{question \: number \: \to 6} \\ \boxed{ w = 72} \\ \boxed{ x =144 } \\ \boxed{ y = 108}

Step-by-step explanation:

y  + w  + y + w = 360 \to \sum \: of \: angles \\ y = \:  \boxed{opp \:  y}  \to \: vertically \: opposite \: angles \: are \: equal \\ w = \:  \boxed{opp \:  w}  \to  \: the \: same \: reason \: as \: y\\ hence \to \\ 2(w+ y) = 360 \\ w + y = 180 \\ but \: 5w = 360 \to \: angles \: at \: a \: point \\ w =  \frac{360}{5}  \\  \boxed{w = 72} \\ therefore \to \\ w + y = 180 \\ 72 + y = 180 \\ y = 180 - 72 \\ \boxed{ y = 108}  \\ hence \:  \boxed{x} \: is \: given \: by \to \\y + x + y = 360 \to \: angles \: at \: a \: point \\108 + x + 108 = 360 \\ x = 360 - 216 \\ \boxed{ x = 144}

Which pair of angles has congruent values for the sin x° and the cos y°?
IRISSAK [1]

Answer:

D

Step-by-step explanation:

We know that if angles x and y are complementary, then sin(x)=cos(y).

This means the measures of the angles have to add to 90 degrees, which is satisfied by the fourth option.

What do the graphs of sine and cosine have in common with the swinging you see?
lilavasa [31]

The relationship between the cosine and sine graphs is that the cosine is the same as the sine — only it’s shifted to the left by 90 degrees, or π/2. The trigonometry equation that represents this relationship is: cosx= sin (x+π/2)

The graphs of the sine and cosine functions illustrate a property that exists for several pairings of the different trig functions. The property represented here is based on the right triangle and the two acute or complementary angles in a right triangle. The identities that arise from the triangle are called the cofunctionidentities.

irakobra [83]

Answer:

y=5x+5

Step-by-step explanation:

y-y1=m(x-x1)

y-(-5)=5(x-(-2))

y+5=5(x+2)

y=5x+10-5

y=5x+5
