Find the degree measure of each angle in the triangle
Karo-lina-s [1.5K]

Answer:

∠L = 43°

∠M = 121°

∠N = 16°

Step-by-step explanation:

<u>Start by setting all sides equal to 180</u>

3x - 5 + 7x + 9 + x = 180

<u>Add like terms</u>

11x + 4 = 180

<u>Solve for x</u>

11x + 4 = 180

      - 4     - 4

      11x = 176

     / 11     /11

        x = 16

<u>Now, plug in 16 for all instances of x on the triangle and solve.</u>

∠L = 43°

∠M = 121°

∠N = 16°

What is the common ratio for the geometric sequence?<br><br> 18, 12, 8, 16/3,…
alex41 [277]

Answer:

2/3

Step-by-step explanation:

Given : A geometric sequence : 18, 12, 8, 16/3,…

Solution :

Each term is found by multiplying the previous term by a constant in a Geometric Sequence .

In a Geometric Sequence  common ratio is denoted by r


r = \frac{a_{n} }{a_{n-1} }


for n = 2


r = \frac{a_{2} }{a_{1} }


⇒r = \frac{12 }{18 }


⇒r = \frac{2 }{3 }


for n = 3


r = \frac{a_{3} }{a_{2} }


⇒r = \frac{8 }{12 }


⇒r = \frac{4 }{6 }


⇒r = \frac{2}{3 }


Thus the common ratio 'r' = 2/3
