Answer:
(-2.5, 1) and (0.5, 5)
Step-by-step explanation:
The main idea is to divide the line into four segments.
so you find the midpoint between (-4, -1) and (2, 7), which is (-1, 3).
then you find the midpoint again between (-4, -1) (-1, 3) and (2, 7) (-1, 3), which is (-2.5, 1) and (0.5, 5).
Answer:
sum of the interior angles x and y gives the exterior angle z
(4n-18)°+(n+8)°=(133-6n)°
4n°-18°+n°+8°=133°-6n°
4n°+n°-18°+8°=133°-6n°
5n°-10°=133°-6n°
5n°+6n°=133°+10°
11n°=143°
11°n/11°=143°/11°
n=13
exterior angle=133-6×13
=133-78
=55
The lateral area for regular pyramid is given by:
A=l√((w/2)²+h²)+w√((l/2)²+h²)
where:
w=width
l=length
h=height
plugging the values in the formula we get:
A=6√((6/2)²+9²)+6√((6/2)²+9²)
A=6√90+6√90
A=12√90
A=113.842 sq. feet
A=
