The interior angle measures of a triangle add up to 180°.

Make ∠A + B + C = 180.

x + (4x) + (5x - 13) = 180
Add all like terms.

10x - 13 = 180
Add 13 to both sides.

10x = 193
Divide both sides by 10.

x = 19.3

Now plug in x into m∠C, (5x - 13).
5(19.3) - 13 = 83.5

The m∠C is 83.5°.

To edit a manuscript, Miguel charges 12 dollars per hour for the first 4 hours and 15 dollars per hour after the first 4 hours.
aleksley [76]

Answer:

C = 12 + 15(x - 4)

C = 15x - 48

Step-by-step explanation:

Let the number of hours = t

The total amount Miguel earns =

C

To edit a manuscript, Miguel charges 12 dollars per hour for the first 4 hours and 15 dollars per hour after the first 4 hours.

C = 12 + 15(x - 4)

Expand the t

C = 12 + 15x - 60

C = 15x - 48

Therefore, an expression for the amount, in dollars, Miguel charges if it takes him t hours to edit a manuscript, where t>4 is given as:

C = 15x - 48
