Answer:
m = 11
Step-by-step explanation:
-2(2 - 4m) = 6(m + 3)
Divide both sides by -2.
2 - 4m = -3(m + 3)
Distribute -3 on the left side.
2 - 4m = -3m - 9
Add 3m to both sides.
2 - m = -9
Subtract 2 from both sides.
-m = -11
Divide both sides by -1.
m = 11
Answer: B
The rotation will go back to the place where the trapezoid started
Answer:
deal with the rectangle first A = l X w
4 X 12 = 48 squared cm
semi circle
Area of a circle πr^2
12/2 = 6, radius = 6
π6^2 = 113.097335
113.097335/2 = 56.5486677
56.5 + 48 = 104.5 squared cm
You can calculate the difference/vector of both points:
then calculate the magnitude/length like pythagoras
Answer/Step-by-step explanation:
27.
✔️Sin 23 = opp/hyp
Sin 23 = t/34
34*sin 23 = t
t = 13.3
✔️Cos 23 = adj/hyp
Cos 23 = s/34
s = 34*cos 23
s = 31.3
28.
✔️Sin 36 = opp/hyp
Sin 36 = s/5
s = 5*sin 36
s = 2.9
✔️Cos 36 = adj/hyp
Cos 36 = r/5
r = 5*cos 36
r = 4.0
29.
✔️Sin 70 = opp/hyp
Sin 70 = w/10
w = 10*sin 70
w = 9.4
✔️Cos 70 = adj/hyp
Cos 70 = v/10
v = 10*cos 70
v = 3.4
