Elan Coil [88]

The circumcenter of a right angled triangle is midpoint of the hypotenuse side.

Determine the midpoint of the hypotenuse.

\begin{gathered} x=\frac{-4+0}{2} \\ =\frac{-4}{2} \\ =-2 \end{gathered}

For y coordinate,

\begin{gathered} y=\frac{2-3}{2} \\ =\frac{-1}{2} \end{gathered}

So, circumcenter of triangle is,

(-2,\frac{-1}{2})

Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if
krek1111 [17]

Answer:

(5,225)

Step-by-step explanation:

The break even point is when the cost equals the revenue.

C=R

15x+150=45x

150=30x

x=5

Plug this back into the original equations to get the y value.

15*5+150=225

or 45*5=225

Supplementary angles are angles whose son is 180. To supplementary angles are such that one angle is 4° less than three times th
zzz [600]

Answer:

The measures of angle are 46 degrees and 134 degrees.

Step-by-step explanation:

We are given the following in the question:

Let the measure of one the of the supplementary angles be x degrees.

Measure of other angle =

(3x-4)\text{ degrees}

Since, the two angles are supplementary, their sum is 180 degrees.

Thus, we can write and solve the equation:

x + (3x-4) = 180\\4x = 184\\x = 46\\(3x-4) = 134

Thus, the measures of angle are 46 degrees and 134 degrees.
