Answer:
h = 4.5 inches
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) h
We know A b1 and b2
20.25 = 1/2 (5+4)*h
20.25 = 9/2 h
Multiply each side by 2/9 to isolate h
2/9 * 20.25 = 2/9 *9/2 h
4.5 =h
Answer:
When 1 millimeter on the map is equivalent to 1 kilometer on the ground, the map scale is 1:100000.
Step-by-step explanation:
X = 6
9/12 = 0.75
6/8 = 0.75
D+100+40=180
d=180-100-40=40 (sum of all angles)
e= 100+40= 140 (exterior angle)
180-140=40
C+50+40=180
C=180-50-40= 90 (right angle)
A=50
B=180-90-50= 40
1 24
2 .41
3 180
4 2000
5 46
6 .18
7 60.5666
8 6.5
9 128
10 .8
11 3.628739
12 4000
