Question of mathematics. Please Help!?
I have three questions. Could you explain how? The hands of a clock have lengths of 6 cm and 8 cm. Calculate the distance between the tips of the hands at 8 pm. I have no idea how to even draw the next. From the lighthouse of L, a ship A is 4 km with an inclination of 340 ° and a vessel from B to 5 km with an inclination of 065 °. Calculate the distance AB. And finally .... When I'm at the point X, the angle of elevation of the top a tree T is 27 °, but if I walk toward the tree 20 meters to the point Y, the elevation angle is 47 ° then the distance TY-Search-Find the tree height Please help!
1) That the 2 points be A and B and central clock C. At 8 pm, the angle of the tip btwn clock (CPF) will be 120 degrees.You know the length of the 2 sides of the triangle formed.ie AC & BC (6 and 8 cm, respectively) In accordance with Rule Breast AB / sin 120 = AC / sin ABC = BC / sin BAC 2) It is not clear, make sure your question is correct, because otherwise give a straight answer 1 kilometers (5 km - 4 km) 3) What will be the height of the tree TOX = 90 degrees TXO = 27degrees so OT = OX * lly 27, OT = 0Y * 47 Tan y = ox - 20 well, so * 27 = OX (OX-20) * tan 47 from this or get OX well, height tree = OT = OX * TAN 27 also, OT = TL * FREE 47 Thus, TL = OT / 47 NO Hope this helps ... cheers
