$45
Step-by-step explanation:
4 lbs = $18
2 lbs = $9
10 lbs = $45
Answer:
BCD = ECD
Step-by-step explanation:
they would equal the same thing because it is still the same shape
Sin60 =b/10
<span>√3/2 = b/10
</span>b = <span>√3 / 2 (10)
</span>b = 5<span>√3
</span>
d^2 = 10^2 - (5√3)^2
d^2 = 100 - 75
d^2 = 25
d = 5
sin30 = b/a
1/2 = 5√3 / a
a = 5√3 (2)
a = 10√3
c^2 = (10√3)^2 - (5√3)^2
c^2 = 300 - 75
c^2 = 225
c = 15
so
a =10√3, b = 5√3, c = 15,d = 5
answer is
D. last choice
DBH make a triangle.
The three inside angles of a triangle need to equal 180
H = 180 - B - D
H = 180 - 39 - 36 = 105
H and X make a straight line that equals 180 degrees
X = 180 - H
X = 180 - 105 = 75 degrees.
Rise over run is 7 over 2 so 7/2 is the slope
