Figure ABCD is a parallelogram with point C (3, -2). What rule would rotate the figure 90 degrees clockwise, and what coordinate

would be the output for point C'?
(x, y) → (−y, −x); C' (2, −3)

(x, y) → (y, −x); C' (−2, −3)

(x, y) → (y, x); C' (−2, 3)

Please help I'm almost done the test and need this and one other question ​
PolarNik [594]

Answer:

z=68

Step-by-step explanation:

Use the formula 180\times(n-2) to find the sum of the angles in a polygon, given <em>n</em> sides. This formula tells us the angles of this pentagon must add to 540 (180\times(5-2)=540).

So, we can setup an equation:

70+2z+11+119+z+2z=540

Solve for z:

200+5z=540 Combine like terms

5z=340 Subtract 200

z=68 Divide by 5

Therefore, the value of z = 68.

What is the value of c?<br> O 4 units<br> O 5 units<br> O 6 units<br> O 7 units
Aleksandr [31]

The value of c is 5 units.

Step-by-step explanation:

Given,

WY = a =  4

ZY = b = 3

As WYZ is forming a right angle triangle, therefore, we can use pythagorean theorem to find the value of c

a^2+b^2=c^2\\(4)^2+(3)^2=c^2\\16+9=c^2\\c^2=25

Taking square root on both sides

\sqrt{c^2}=\sqrt{25}\\c=5

The value of c is 5 units.

Keywords: triangle, square root

The area of a trapezoid is 216 in2 and it two bases are 14 and 22 inches long. Find the height of the trapezoid.
artcher [175]

Answer:

12 inches

Step-by-step explanation:

The formula for a trapezoid is

A = 1/2(a +b)h

The formula to find the height =

h = 2A/a + b

A= 216 in²

a =14 in

b = 22 in

Hence,

h = 2 × 216/14 + 22

h = 12 inches

The height of the trapezoid = 12 inches
