Answer:
x = 6.6; DE = 16.6
Step-by-step explanation:
Assume the diagram is like the figure below.
1. Calculate the value of x
In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the triangle into two similar triangles.
Thus, ∆CDF ~ ∆FDE, and
2. Calculate the length of DE
DE = 2x + 3 = 2(6.6) + 3 = 13.2 + 3 = 16.2
Answer:
Area of the parallelogram= 
Step-by-step explanation:
Area of a parallelogram = Length * Perpendicular height
To find the perpendicular height of the parallelogram:
Using given angle 60° in the triangle.
Area of the Parallelogram:
Area of the parallelogram=
Answer:
Step-by-step explanation:
first we need to find the slope bu using the slope formula and ur two sets of points
slope = (y2 - y1) / (x2 - x1)
(7,1)...x1 = 7 and y1 = 1
(-12,-6)....x2 = -12 and y2 = -6
now we sub
slope = (-6 - 1) / (-12 - 7) = -7/-19 = 7/19
now...in y = mx + b form, the slope will be in them position
y = mx + b
slope(m) = 7/19
use either of ur points.....(7,1)...x = 7 and y = 1
now we sub and find b, the y int
1 = 7/19(7) + b
1 = 49/19 + b
1 - 49/19 = b
19/19 - 49/19 = b
- 30/19 = b <======= ur y int
so ur equation is : y = 7/19x - 30/19
