Zanzabum

Answer:

187.06 units²

Step-by-step explanation:

Area of kite:

½ × d1 × d2

½d1 = 18sin(30)

½d1 = 9

d1 = 18

d2 = 9/tan(60) + 18cos(30)

= 12sqrt(3)

Area = ½ × 18 × 12sqrt(3)

108sqrt(3) units²

187.0614872 units²

Find the equation of the line that passes through (1,2) and is perpendicular to
uysha [10]

Answer:

Remember that the slope of perpendicular lines are negative reciprocals of each other.

Step-by-step explanation:

y = 1 - 2x     the slope is -2     the value of the x term.

So the slope of the new line using point (- 1, 2)  is  1/2.

Now use y = mx + b where y = -1, x = 2, and m = 1/2 .

y = mx + b

-1 = 1/2(2) + b                solve for "b", the y-intersect

-1 =  1 + b

-2 = b

The line that is perpendicular to y = 1 - 2x  is  y = 1/2x - 2
