Answer 1

a = 36.37 cm

c = 18.19 cm

Explanation:

to find a, use tan

⇒ tan =
`(opposite)/(adjacent)`

⇒ tan 60 =
`(21)/(a)`

tan of 60 is 1.732

⇒ 1.732 =
`(21)/(a)`

multiply 21 on both sides

⇒ 1.732 x 21 =
`(21)/(a)`x 21

⇒ 36.37 = a

to find c, use sine

⇒ sine =
`(oppsosite)/(hypotenuse)`

⇒ sine 60 =
`(21)/(c)`

sine of 60 is 0.866

⇒ 0.866 =
`(21)/(c)`

muliply 21 on both sides

⇒ 0.866 x 21 =
`(21)/(c)` x 21

⇒ 18.19 = c
