Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m∠LOM+m∠MON=m∠LON ----> by angle addition postulate
we have
m∠LOM=2x°
m∠MON=x°
m∠LON=90° ----> is a right angle
substitute the values

solve for x


Let the melting point be x degree C.
-188-x= 32
-x=32+188
-x=220
x= -220
Hence, the melting point of fluorine is -220 degree C.
7 + 7 + (-1)
7 + 7 - 1

Simple interest= prt
=806.68 (.0525)(1)
=42.35
Balance=investment + interest earned
806.68+42.35=$849.03
