Use the ratio of cosine.
cos x = adj/hyp
cos 60 = x/14
14 (cos 60) = x
7 = x
length of DF is 7.
Hope this helps :)
<u>Answer:</u>
Area of kite is 30 sq units.
<u>Solution:</u>
Note: Refer the image attached
From the given,
AC = 10 ; BD = 6
Kite is a quadrilateral as it has two equal adjacent sides.
The formula for the area of quadrilateral (kite) when both the diagonals are given is
Here AC is and BD is
On substituting the given values we get
Answer:
How can we answer when no graph illustrations is shown
Step-by-step explanation:
8 is the answer.
Basically for 3 to equal 6 you multiply it by 2, so if you do that to 4, you get 8.
To check ur answer u can do 8:6 can be simplified to 4:3 if you divide both by 2.
Answer:
(3) 11
Step-by-step explanation:
A line perpendicular to one with a slope of -2 will have the opposite reciprocal slope: -1/(-2) = 1/2.
The point-slope equation of the line through (3, 9) with slope 1/2 is ...
y -9 = 1/2(x -3)
Then for point (7, k) on the line we have ...
k -9 = 1/2(7 -3)
k = 9 +2 = 11
The value of k is 11.
