The value of WZ in the given similar polygons, is 72
What are similar polygons?
When polygons are similar their corresponding angles are congruent and their corresponding sides are proportional.
Given that, quadrilateral ABCD and quadrilateral WXYZ are similar,
The order of the proportionality statement tells us which angles and sides are corresponding.
To solve, set up a proportion.
AD/WZ = DC/ZY
12/WZ = 6/36
Cross multiply.
6(WZ) = 12x36
6(WZ) = 432
Divide both sides by 6
WZ = 72
Hence, the value of WZ is 72

94 m²
Step-by-step explanation:
The lateral area of a right circular cone if the diameter of the base is 4m and the slant height of the cone is 15m. Solution: Lateral Area = pi*r ( h²+r²) r = 4/2 r = 2 meters Lateral Area = 3.14*2 ( 15²+2²) Lateral Area = 94 m²
Answers
Answer:
Area = y² + 2x + 1
Step-by-step explanation:
You have to combine like terms:
The little square is 1 unit, so 1
The two bars are each worth x, so 2 * x = 2x
The big square is y²
The total area is the sum of all terms:
Area = y² + 2x + 1

All the angles around a point on one side of a line add up to 180°.
A). Look at the angles at point-D, above the line.
You've got 40° and you've got a right angle ... 90°.
Those two angles add up to (40° + 90°) = 130°.
How much more is needed to make 180° ?
(180° - 130°) = 50°. That's angle 'x'.
B). Look at the angles at point-C, below the line.
You've got 55°.
How much more is needed to make 180° ?
(180° - 55°) = 125°. That's angle 'y'.
m∠x = 50°
m∠y = 125°
m∠x + 40° = 90°
x + 40 = 90
- 40 - 40
x = 50°
m∠y + 55° = 180°
y + 55 = 180
- 55 - 55
y = 125°
a) y = -1
b) y = 3
c) y = x -1
d) y = 3x - 1

Step-by-step explanation:
The general form of a straight line is , where m = slope and b = y-intercept.
Ques 1: We are given that the line passes through (0,2.5) and (4,2.5).
Then the slope of the line is given by,
Then, the y-intercept is given by,
That is, the equation of the line is
Since, 'Two parallel lines have equal slope'.
Then, the line parallel to have slope 0 i.e.
.
As, the line passes through the point (3,-1) i.e. y= -1 for any value of x.
Then, the equation of line is
So, option A is correct.
Ques 2: We are given that the line passes through (-2,0) and (0,-1).
Then the slope of the line is given by,
Then, the y-intercept is given by,
That is, the equation of the line is
Since, 'The product of slopes of two perpendicular lines is -1'.
Then, we have,
The line perpendicular to have slope 2.
As, the line passes through the point (-1,2) with slope 2.
The y-intercept is given by,
Thus, the equation of the line is
So, option A is correct.
The graph of the first line is 0. The graph of the second line will also be equal to 0. Replacing in the general equation of a line y=mx+c;
y=(0)x+c
y=c
Using the point (3,-1)
-1=c
y=-1
