Hey there! :)

Answer:

m∠y = 55°.

Step-by-step explanation:

Begin by solving for x since y and x are supplementary angles.

Recall that all of the angles in a triangle must sum up to 180°. Therefore:

180 - 30 - 25 = 125°.

x = 125°, therefore:

180 - 125 = 55°.

m∠y = 55°.

zimovet [89]

For this case we define the following variable:

  • <em>x: number of stamps </em>

We now write the equation that models the problem:

\frac {3} {4} x + 12 = 39

From here, we clear the value of x.

We have then:

\frac {3} {4} x = 39-12\\\frac {3} {4} x = 27\\x = (\frac {4} {3}) (27)\\x = (4) (9)\\x = 36

Answer:

The number of stamps he has is:

x = 36
