Answer:

The answer is option C i.e; y=0.9x-45

Step-by-step explanation:

When you substitute the values of x you have to get same values as given in the table

For example: substitute x=50 in the equation y=0.9x-45

Y= 0.9(50)-45

Y= 45-45

Y=0

What is the measure of angle C?

quester [9]

Answer:

C = 10.39

Step-by-step explanation:

We know that the sin of an angle is the opposite side over the hypotenuse

sin C = 22/122

sin C = 11/61

Take the inverse sin of each side

sin ^-1 (sin C) = sin ^-1 ( 11/61)

C = 10.38885782

To the nearest hundredth

C = 10.39

If the sin 60 agrees equals the square root of three over two which statement is true

torisob [31]

Given that
$\sin60^o= \frac{ \sqrt{3} }{2}$

$\cos 30^o =\sin(90-30)^o=\sin60^o=\frac{ \sqrt{3} }{2}$ ,

$\cos 120^o =-\sin(180-120)^o=-\sin60^o=-\frac{ \sqrt{3} }{2}$ ,

$\cos30^o\neq0$ ,

$\cos120^o\neq0$

Therefore, the true statement is
$\cos 30^o =\sin(90-30)^o=\sin60^o=\frac{ \sqrt{3} }{2}$ ,
because the cosine and sine are complements.
