2x+8=20
2x=20-8
2x=12
12/2=x
6=x
Answer:
5 inches
Step-by-step explanation:
we know that
The scale drawing is
using proportion find out the width of the great room on her plan
since the polygon has 8 chambers the angle of one chamber = 360/8 = 45°
so the angle WOP = 45°
now drawing a imaginary line which seperates the triangleWOP into half
so the angle of imaginary line is 45/2 = 22.5
sin(theta) = opp/hyp
since WP (opp) is unknown. take as x
sin(22.5) = x/44
0.383×4 = x
x = 1.532 (app) = 1.5 cm
perimeter = 1.5 × 8
= 12 cm
area of triangle WOP = 2×1/2 ×bh = bh
= 4×1.5
= 6 cm²
so the area of regular polygon = 8× area of a triangle
= 48 cm²
Answer: Brailiest plz?
31
Step-by-step explanation:
(3)(9)+4=31
Answer:
-2
Step-by-step explanation:
to find the slope from to points you can follow this equation
m=y2-y1 / x2-x1
so plug in the points
1-3/ 1-0
-2/1
-2
