Answer:61.3
Step-by-step explanation:
Using the Law of Sines, you get this formula
sin(angleA)=(a*sin(angleB))/b
sin(angleA)=(14*sin(70)/15)
sin(angleA)=(.88)
angleA=sin-1(.88)
angleA=61.3
Step-by-step explanation:
60% = 18 +
20% = 6 ( cos its 1/3)+
20% = 6 =
100% = 30

Answer: The fraction x = 1/2 or its equivalent decimal form x = 0.5
================================================
Work Shown:
AE = 2*(BD)
4x+8 = 2*(4x+3)
4x+8 = 8x+6
8-6 = 8x-4x
2 = 4x
4x = 2
x = 2/4
x = 1/2
x = 0.5
note: the first equation is set up basically saying that AE is twice that of BD; put another way, BD is half as long as AE. This is one property of midsegments. Another property is that AE and BD are parallel.
another note: if x = 0.5, then AE = 4*x+8 = 4*0.5+8 = 10 while BD = 4*x+3 = 4*0.5+3 = 5, showing that AE is indeed two times longer than BD.
assuming that all the coins are homogeneous, the probability of each coin be on heads is 1/2. so:
