When Ryan started a daily exercise routine, he lost 18% of his weight. He now weighs 180.4 pounds.
of What was Ryan's weight before he began to exercise?

Please help me and show your work on how you got it so I can learn please):!

Take his now weight which is 180.4. Divide it by 0.82 because 18% off is 82%. So 180.4/0.82= 220 pounds

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
