Answer:

Step-by-step explanation:
This is a 45°-45°-90° triangle. The two legs are the same length, and the hypotenuse is that length times the square root of two:

Therefore, the value of x is 11.
You can double-check using the sine ratio:

Insert the values:

Insert the equation into a calculator:

:Done
*It's important to know that, when working with trigonometry ratios, the hypotenuse is never considered the adjacent or opposite side, and the 90° angle is never used in the ratios.
Answer:
5/8
Step-by-step explanation:
Aquí, queremos encontrar la suma al infinito de la progresión geométrica, dado el primer término y la razón común Matemáticamente, eso sería;
S = a/1-r
S = 1/2/(1-1/5)
S = 1/2/4/5
S = 1/2 * 5/4
S = 5/8
