Given: △abc with side lengths a, b, and c, and height h
prove: area=1/2 ab sin c
triangle a b c has sides a b c. a vertical dashed line extends from angle b perpendicular to side b.
drag and drop the statements into the boxes to correctly complete the proof.
statement: reason
△abc with side lengths a, b, and c, and height h: given
: triangle area formula
: definition of sine
asinc=h: multiplication property of equality
area=1/2 ba sin c: substitution property
: commutative property of multiplication
options
area = 1/2 ab sin c
area = 1/2 bh
area = 1/2 ah
sin c = h/a
sin c = h/b

Malia is observing the velocity of a cyclist at different times. after two hours, the velocity of the cyclist is 15 km/h. after five hours, the velocity of the cyclist is 12 km/h. part a: write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist at different times. show your work and define the variables used. (5 points) part b: how can you graph the equations obtained in part a for the first 12 hours? (5 points) if you can try and make this as little confusing as you can
