Answer:
The length of the radius of circle is 16.25 cm
Step-by-step explanation:
we know that
If CD is tangent to circle A at point D
then
the segment CD is perpendicular to the radius AD
and
ACD is a right triangle
so
Applying the Pythagorean Theorem
we have
substitute
solve for r
C=<span>30000
and the other one do u want me to solve for x or r?</span>
1/4 of 1/2 of a pizza is an 1/8 of a pizza.
(1/4)*(1/2)=1/8
We can notice the triangle on the square, hypotenuse is 8m and the base is half of the lengt of the square we will name it x
then
we can use pythagoras to solve
where a and b aer sides of the triangle and h the hypotenuse
replacing
the length of x is half of the side of the square then the side of the square is
each side of the square is 8v2 meters
Area
we use formula of the area
<em>area of the square is 128 square meters</em>
Perimeter
we use formula of the perimeter
perimeter of the square is 32v2 meters
Answer: Parallel: y= -4x+3, or any equation with a y-intercept that isn't -14;
Perpendicular; y=1/4x+3 or any equation with the same slope
Step-by-step explanation:
Parallel lines have the same slope but different intercepts
Perpendicular lines have the opposite reciprocal as a slope
