Answer:
k°=140°
Step-by-step explanation:
Triangles have 180° in total, use this to find the missing angle in the shaded triangle:
64°+76°+x°=180°
x°=40°
Know that lines also have 180° in total, therefore x°+k° = 180. Apply this:
40°+k°=180°
k°=140°
See the attached figure to better understand the problem
we know that
AM=MD
so
triangle AMD is an isosceles right triangle
therefore
its height is half its width.
Then
AB = (1/2)AD----------Equation 1
Perimeter=2*[AB+AD]=34 in ---------> AB+AD=17-------> Equation 2
I substitute 1 in 2
(1/2)AD +AD = 17
(3/2)AD=17
AD=17*2/3----------> AD=34/3-------> 11 1/3 in
AB=(1/2)AD--------> AB=(1/2)*34/3--------> AB=17/3-------> AB=5 2/3 in
the answers are
AD=11 1/3 inAB = 5 2/3 in
The point-slope form would be written as:
y - y1 = m(x-x1)
<span>1. Select the proper equation in point-slope form for the given point and slope.
Point: (1, 9); Slope: 5
y – 9 = 5(x – 1)
Question 2.2. Select the proper equation in point-slope form for the given point and slope.
Point: (–8, 3); Slope: 6
y – 3 = 6(x + 8)
Hope this answers the question. Have a nice day.</span>
True, because they make up the two line segments make up the right angle
4n+78n-3/4=942
l
82n - 3/4=942
+3/4 +3/4(.75)
82n=942.75
divide 82 by both sides
n = 11.49 or 11.5
