Question

ABCD is a square. Find the length of BT

Answer 1

BT should equal 8

Proof:

Triangle CDT is a 45 45 90 triangle.

The leg of the triangle = base * (1 / sqr root (2))

The leg of the triangle = 11.3 * (1 / 1.4142135624 )

The leg of the triangle = 11.3 * 0.7071067812

CT = BT = 11.3 * .7071067812 = 8
