Answer: the measure of the third triangle is 75 degrees.

Step-by-step explanation:

Let the measure of the third angle be x degrees.

The sum of the three angles in a triangle is 180 degrees.

One of the angle measures 30 degrees, and the second angle measures 75 degrees. Therefore,

30 + 75 + x = 180

105 + x = 180

Subtracting 105 from the left hand side and the right hand side of the equation, it becomes

x = 180 - 105 = 75 degrees

75 degrees

Step-by-step explanation:

30 + 75 = 105

180 - 105 = 75

Which of the following numbers is both a perfect square and a perfect cube?
Marat540 [252]

Answer:

531441

Step-by-step explanation:

We can find by   factorization

531441 = 9 * 9 * 9 * 9 * 9 *9 = (9*9*9) * (9*9*9)

\sqrt[3]{531441}=\sqrt[3]{9*9*9*9*9*9}  =9*9 = 81\\\\\\\sqrt{531441}=\sqrt{(9*9)*(9*9)*(9*9)}=9*9*9=729
