Aseamstress is making a decorative pillow and wants to cover both sides of the pillow with special fabric. the pillow is
in the shape of a triangle with vertices (7.7) (10.3) (7.3). how many square inches of fabric will she need if each unit on
the grid is one inch?
06 m²
7 in
15

The three points form a right triangle with legs length 3in and 4in. So, the area is

So, both sides of the pillow will require 12 squared inches.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
