Answer:
No
Step-by-step explanation:
Given:
y is directly proportional to x.
when ![x=5](https://tex.z-dn.net/?f=x%3D5)
To find:
The equation that connects y with x.
Solution:
It is given that, y is directly proportional to x. So,
![y\propto x](https://tex.z-dn.net/?f=y%5Cpropto%20x)
...(i)
Where, k is the constant of proportionality.
We have,
when
. Substituting these values in (i), we get
Divide both sides by 5.
Substituting
in (i), we get
Therefore, the required equation is
.

Answer:
x = 116º
Step-by-step explanation:
the sum of angles on the same side equals 180º so:
x + 64º = 180º subtract 64º from both sides
x = 116º
