Answer:

c = - 20

Step-by-step explanation:

Given

- 21 = \frac{1}{2} c - 11 ( add 11 to both sides )

- 10 = \frac{1}{2} c ( multiply both sides by 2 to clear the fraction )

- 20 = c , that is

c = - 20

Answer:

x = 200/3

Step-by-step explanation:

Apply Thales theorem, we have:

80/(2x) = 60/27

Let's simplify both sides:

40/x = 20/9

or

x/40 = 9/20

Multiplying both sides by 40, we have:

(40/40)x = (20/9)*40

Let's simplify one more time:

x = (20*40)/(9)

or

x = 200/3

Hope this helps!
