You cannot assume the angles add to 90, but you know since BD is an angle bisector that ABD is equal to DBC, or x-5=2x-6

x=1. this is the correct solution to the equation but gives negative angles when plugged in which isn't possible. there must be something wrong work the question

The value of 12pi over 10pi times 5pi Over 6pi is closest to the whole number (blank). Find the blank
lisov135 [29]

Given:

The expression is

\dfrac{12\pi}{10\pi}\times \dfrac{5\pi}{6\pi}

To find:

The value of the given expression closest to the whole number.

Solution:

We have,

\dfrac{12\pi}{10\pi}\times \dfrac{5\pi}{6\pi}

Cancel out the common factors from each fraction.

=\dfrac{6}{5}\times \dfrac{5}{6}

=\dfrac{6\times 5}{5\times 6}

=\dfrac{30}{30}

=1

Therefore, the value of the given expression is 1.
