x is 53
angle PQD is equal to APQ. so its 62 degrees
PRC and PRD are supplement so their sum is 180.
PRD=115 PRC= 180 -115= 65
the sum of the angles of a triangle is equal to 180. so:

good luck
Y = 0.5x + 16.5
parallel so y = 0.5x + c
12 = 0.5 * -9 + c
12 = -4.5 + c
c = 16.5
y = 0.5x + 16.5
Mark brainliest please
Answer:
For this case, we have the following equation (according to the comments):
First, we factor the quadratic expression in the denominator:
Then, we multiply both sides of the equation by (a-2) (a + 2):
Later, canceling similar terms we have:
We do distributive property on the left side of the equation:
By grouping variables and constant terms we have:
Rewriting we have:
Finally, by clearing "a" we have:
Note: the value of a is a extraneous solution because it makes the denominator of the original equation equal to zero.
Answer:
the student correct, but the value of a= -2 is an extraneous solution
Answer:
pi
Step-by-step explanation:
The radius of the circle is 10 units
The circumference of a circle is given by the formula:
C = 2 * pi * r
The diameter of a circle is twice the radius
d= 2r
We want the ratio of the circumference to the diameter
C/d = (2*pi*r)/ 2r
Canceling out the 2 and the r, we are left with pi
C/d = pi

x = -1
