Find x <br><br><br> please help me
Mrac [35]
X = 30 I think as angle on straight line = 180 so 180-103 = 77 , 30+43 = 73 , 77+73 = 150 , 180-150= 30 , then opposite angles are the same so therefore x = 30 degrees

Y is inversley proportionaly to x. when y=7, x=9
mrs_skeptik [129]

The equation is y = 63/x

And y = 3 when x=21

Step-by-step explanation:

When y varies inversely with x, The inverse proportion is given by:

y ∝1/x

When the proportionality symbol is removed, a constant of proportionality is introduced

y = \frac{k}{x}

Putting y = 7 and x = 9

7 = \frac{k}{9}\\k = 9*7\\k = 63

So,

y = \frac{63}{x}

Putting x =21

y = \frac{63}{21}\\y = 3

Hence,

The equation is y = 63/x

And y = 3 when x=21
