Answer: B. 164
The value of y =30
The value of CD = 164
Step-by-step explanation:
Properties of isosceles trapezoid:
- Two sides are parallel.
- The opposite non-parallel sides are equal.
- The diagonals are equal.
Given: ABCD is an isosceles trapezoid with diagonals that intersect at point P. AB || CD
⇒ BC= AD [opposite non-parallel sides]
AC=BD [ Diagonals are equal]
Since and
The value of CD =

Answer:
C) 4x^2 -8x +4[/tex]
Step-by-step explanation:
(-2x+2)^2
we apply (a+b)^2 formula
a= -2x and b= 2
Replace 'a' with -2x and 'b' with 2
(-2x)^2 is 4x^2
option C is the answer
Answer:
radians
Step-by-step explanation:
Arc length and radius is given. So, we need to know the arc length formula for a circle.
That is:
Where s is the arc length
r is the radius
is the angle (IN RADIANS)
We have:
s = 15.5
r = 9
Now, we substitute and find the angle:
The angle, in radians, in 1.72
