Answer:
Step-by-step explanation:
Coordinates of the vertex A → (-4, -6)
Coordinates of the vertex A' → (6, 6)
Since, y-coordinates are same opposite in notation,
Therefore, by the rule of reflection, line of reflection will be a line parallel to y-axis.
And points A and A' will be equidistant from the line of reflection.
Midpoint between A and A' =
=
= (1, 0)
Therefore, x = 1 will be the line of reflection.
Answer:
arc VW = 66°
Step-by-step explanation:
The inscribed angle WXY is half the measure of its intercepted arc WY, so
WY = 2 × 57° = 114°
Arc YX = 180° ( semi- circle ) , then
VW = YX - WY = 180° - 114° = 66°
Answer:
x = 41° , y = z = 74°
Step-by-step explanation:
x and 41 are alternate angles and are congruent , then
x = 41°
the 2 sides of the triangle with vertex = 32° are congruent so the triangle is isosceles with base angles being congruent , then
y = = = 74°
y and z are vertically opposite angles and are congruent so
z = 74°
A variable is a symbol that’s used in a number. It typically uses a variation of letters such as x,y,etc. for instance 3x=6
Answer:
b = 225
Step-by-step explanation:
multiply both members by 15
15 x 15 = (b/15)x 15
b = 225
