1. Find the value of x<br>2. Using complete sentences, describe your

aleksley [76]

Answer:

x = 40

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Consider the triangle on the left and calculate the third angle

Subtract the sum of the 2 angles from 180

third angle = 180° - (75 + 50)° = 180° - 125° = 55°

Consider the triangle on the right

The third angle = 55° ( vertical angles )

Subtract the sum of the 2 angles from 180

x = 180 - (55 + 85) = 180 - 140 = 40

Find the ninth term of the geometric sequence a4= -135,r=-3

Tresset [83]

Answer:

The nth term of the geometric sequence is is 32805

Step-by-step explanation:

The nth term of a geometric sequence is given by

$a_n = a_1 \cdot r^{n - 1}$

Where $a_1\\$ is the first term and $r$ is the common ratio

We are given the fourth term of this sequence

$a_4 = -135$

The common ratio is

$r = -3$

Once we find the 1st term then we can find any other term.

$a_4 = a_1 \cdot r^{4 - 1} \\\\a_4 = a_1 \cdot r^{3} \\\\-135 = a_1 \cdot (-3)^{3} \\\\-135 = a_1 \cdot (-27) \\\\a_1 = \frac{-135}{-27} \\\\a_1 = 5$

So the ninth term of this geometric sequence is

$a_n = a_1 \cdot r^{n - 1} \\\\a_9 = a_1 \cdot r^{9 - 1} \\\\a_9 = a_1 \cdot r^{8} \\\\a_9 = 5 \cdot (-3)^{8} \\\\a_9 = 5 \cdot (6561) \\\\a_9 = 32805$

Therefore, the nth term of the geometric sequence is is 32805
