Question 84 a) AB=BC (given on diagram) XC= 6.2 / 2 XC= 3.1 m BC2 = BX2 + XC2 BC2 = (1.4)2 + (3.1)2 BC = sqrt (11.57) BC=3.4 m (1 dec. pl.) therefore AB= 3.4 m b) Total length of metal = AB + BC + AC + XY + ZY + BX = 3.4 + 3.4 + 6.2 + 1.7 + 1.7 + 1.4 =17.8 m c) Tan...

Soz lyounamu and bored of sc I made a mistake :(

1) Show that (2sin3A + 2 cos3A) / (sin A + cos A ) = 2 – sin2A if sin A + cos A does not equal 0 LHS=2(sin3A + cos3 A) / (sinA + cosA) =2(sin2A + cos2 A) =2(1) =2 =/= RHS :mad:

I "had to" get rid of them because we moved houses, and they were not being used, so they just took up space.
