a = 36.37 cm

c = 18.19 cm

Step-by-step explanation:

to find a, use tan

⇒ tan =

⇒ tan 60 =

tan of 60 is 1.732

⇒ 1.732 =

multiply 21 on both sides

⇒ 1.732 x 21 = x 21

⇒ 36.37 = a

to find c, use sine

⇒ sine =

⇒ sine 60 =

sine of 60 is 0.866

⇒ 0.866 =

muliply 21 on both sides

⇒ 0.866 x 21 = x 21

⇒ 18.19 = c

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
