Given:
.
To find:
The value of r.
Solution:
We have,
.
We know that the radius is perpendicular to the tangent at the point of tangency
AD is the tangent and CD is the radius. So, CD is perpendicular to AD at point D, i.e.,
.
Using Pythagoras theorem, we get




On further simplification, we get



Therefore, the value of r is 9.
Answer:
4
Step-by-step explanation:
The highest/exponent of the variable is the degree of the polynomial.

Here, the highest degree of the variable m is 4
So, degree of the polynomial = 4
Step one- distribute
6y-9=27
Step 2- subtract 9 on both sides
6y=18
Step 3 divide on both sides
Y=3
