Answer:
Step-by-step explanation:
since 105 + z is a straight line we know it equals 180 so we can use this equation
180 = 105 + z
simplify
75 = z
the since we know that all quadrilaterals equal 360 degrees we can add our two given number and z then subtract from 360:
102 + 85 + 75
= 262
now subtract
360 - 262
= 98
y = 98

Answer:
k = 1
Step-by-step explanation:
=> y ∝ x²
So, y = kx² ----------------------------(1)
<u><em>Where k is the constant of proportionality</em></u>
Now,
y = 9 when x = 3
Putting in (1)
=> 9 = k(3)²
=> 9 = k(9)
Dividing both sides by 9
=> k = 1
