Question

3) The angles of a triangle are in a ratio of  1:1:2. Find the ratio of the sides opposite these angles.

a) 1:1:2

b) 1:3‾√:2

c) Cannot be determined.

d) 1:1:2‾√

e) 2‾√:2‾√:1

f) None of the above

4)

Draw acute △ABC with  m∠A=30∘. Draw altitude BD⎯⎯⎯⎯⎯⎯⎯⎯ from B to AC⎯⎯⎯⎯⎯⎯⎯⎯. If BD=2, find AB.

a) 23‾√

b) 23‾√3

c) 43‾√3

d) 22‾√

e) 4

f) None of the above

5)

Assume that WZ=XY . Which of the following statements are true? (Assume that W, Z, X, Y, and F are nonzero real numbers, and assume that all expressions have nonzero denominators.)

Create an answer using the numbers associated with the true statements. For example, if only 1, 2, and 5 are true, then the answer is 125; if only 3 and 5 are true, then the answer is 35, etc.

1.   W−Z over Z = X−Y over Y (over = ex.1/2) or divided by. I don't know how else to put it. sorry.

2.   W+X over Z+Y = W over Z

3.   W+Z over Z = X+Y over Y

4.   W−F over Z = X−F over Y

5.   W+F over Z = X+F over Y

6.   W+F over Z+F = X+F over Y+F

a) 14

b) 123

c) 13

d) 346

e) 1235

f) 135

g) None of the above
