a) Angle XBC = 55 because XY is parallel with BD

b) As given, XB = XC, so that triangle XBC is the equilateral triangle.

As XBC is equilateral triangle, angle XBC is equal to angle XCB

Angle XBC = 55° => Angle XCB = 55°

In a triangle, the total value of three corners are equal to 180°

So that: Angle XBC + Angle XCB + Angle BXC = 180°

=> 55° + 55° + Angle BXC = 180 °

=> Angle BXC = 70°

Area ( If you know the circumference) :
C^2 / (4×3.14) Brackets are important!
So you have to type :
53.38^2/(4×3.14)

Are 2/7 and 6/21 equivalent ratios
ra1l [238]
6 / 2 = 3
21 / 7 = 3

Yes, 2/7 and 6/21 are equivalent ratios.  The second number is simply the first number tripled.

Given that (-6,2) is on the graph of f(x) find the corresponding point for the function f(1/4x).
Dafna1 [17]
Answer: (-24,2)

=======================================

Work Shown:

The y coordinate stays the same. Only the x coordinate will change.

(1/4)*x = -6
x = -6*4
x = -24 is the new x coordinate
Plugging x = -24 into f((1/4)x) leads to f(-6) = 2

Line segment BC will be reflected over line m to form line segment BC. Which of the following statements must be true?
Len [333]

Answer:

<u>Option A</u>

Step-by-step explanation:

To reflect line segment BC over line m, BB' will be perpendicular to the line m

and line m bisector of BB'.

<u>So, the correct answer is option A</u>

A) Line m is the perpendicular bisector of line segment BB' and the line segment CC'

<u>Option b is wrong</u> , it is impossible for the line B'C' to be perpendicular to line BC. B'C' is the image of BC.

<u>Both option c and d is wrong</u> because the perpendicular distance from b to the line m not equal to the perpendicular distance from c to the line m.
