David proved the law of cosines with reference to ∆abc using a different method. arrange the steps of his proof in the correct sequence. (on simplification) therefore, . (on simplification) (transitive property) similarly, prove that and . (on simplification) in , (pythagorean theorem) in , (pythagorean theorem) draw a perpendicular, , from b to side ac. let and . therefore, .

image of solution attached below

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
