The sum of the interior angle measures is 180°. Find the value of X.
Dafna1 [17]

Answer:

Step-by-step explanation:

By the Triangle Angle-Sum Theorem, the angles of a triangle add up to equal 180, regardless of the size of the triangle.  We are given the angle measures, so adding them together and setting them equal to 180 is

60 + 3x + x + 20 = 180 and, combining like terms,

4x + 80 = 180.  Subtracting 80 from both sides,

4x = 100 so

x = 25

Complete the pattern 486,162,54,18
neonofarm [45]
Each successive number is divided by 3.

\dfrac{486}3=162
\dfrac{162}3=54
\dfrac{54}3=18

and so on. The next number in the sequence is \dfrac{18}3=6, and in general, you have a geometric sequence defined recursively by

\begin{cases}a_1=486\\\\a_n=\dfrac13a_{n-1}&\text{for }n>1\end{cases}

and a closed form

a_n=\dfrac13a_{n-1}=\left(\dfrac13\right)^2a_{n-2}=\cdots=\left(\dfrac13\right)^{n-1}a_1=\dfrac{486}{3^{n-1}}
