The measures of the three angles of a triangle are given by 4x -1, 2x + 1, and 6x. What is the measure of the largest angle? A 15° B 31° C.59° D. 90°​

D. 90°

Step-by-step explanation:

6x + 4x - 1 + 2x + 1 = 180

12x = 180

x = 15

6x = 6 * 15 = 90

D. 90°

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
