What is the value of x? Enter your answer in the box. x = ___

1 answer:

5 0

Answer:

x=8

Explanation:

The picture tells us that the triangle is equilateral (this means that each angle is 60°). We can assume this because each side has been marked with the same line.

Because each angle is equal to 60°, this means that:

7x+4=60

Now solve for x:

7x=56
x=8

I need help with geometry:

nikklg [1K]

Answer:

x = 5

Step-by-step explanation:

6/18 = x/(20-x)

1/3 = x/(20-x) Multiply both sides by 20-x

(20-x)/3 = x Multiply both sides by 3

20-x = 3x Add x in both sides

20 = 4x Divide both sides by 4

5 = x

Identify whether the series summation of 8 open parentheses 5 over 6 close parentheses to the i minus 1 power from 1 to infinity

Leto [7]

$\displaystyle\sum_{i=1}^\infty\8\left(\dfrac56\right)^{i-1}$

This is a geometric series with a common ratio between successive terms that is less than 1 in absolute value. This means the series will converge. The value of the sum is $\dfrac8{1-\frac56}=48$ .
