$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: m \overbrace{DB} + m \overbrace{TB} = 180 \degree$

[ linear pair ]

$\qquad \tt \rightarrow \: m \overbrace{DB} + 90 \degree = 180 \degree$

$\qquad \tt \rightarrow \: m \overbrace{DB} = 180 \degree - 90 \degree$

$\qquad \tt \rightarrow \: m \overbrace{DB} = 90 \degree$

i thought of a number. if i subtract 6 from it and multiply the difference by 4 the result is 36. find the number that i thought

SVEN [57.7K]

Since the difference*4=36, the difference = 9
since the number-6= the difference, the number-6=9
Thus the number is 15
