Answer: 9 miles I think but I dont know where her house is exactly.
2cosx=2sin2x. Sin2x is an identity for 2sinxcos. So 2[2sinxcosx] gives you 4sinxcosx. 2cosx=4sinxcosx. Divide 2cosx on both sides and gives you 2sinx=0 and divide again, sinx=0. Sinx is 0 at 0 and 360 degrees, or pi and 2pi. So thats what x would be. 0,360,pi,2pi.
Answer:
700,000+80,000+5,000+400+20
Total length of the wire = 2*13 + 2*5 = 26 + 10 = 36 in.
so length of each side of the triangle would be 36/3 = 12 ins.
