Drag each tile to the correct box. 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) in , (pythagorean theorem) in , (pythagorean theorem) (transitive property) therefore, . (on simplification) draw a perpendicular, , from b to side ac. let and . therefore, . (on simplification) similarly, prove that and .

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

well what did you do it matters what you did : )

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
