Answer: 42cm

Step-by-step explanation:

Using the formula

(Hypotenuse^2)= (Opposite^2) + (Adjacent^2)

Hypotenuse= 58cm

Opposite= 40cm

Adjacent= x

Therefore

(58^2)= (40^2) + (x^2)

3364= 1600 + x^2

3364-1600= x^2

1764= x^2

x= 1764^1/2

x= 42

Adjacent= 42cm

Answer:

Step-by-step explanation:

If you are looking for the value of x, use the Pythagorean Theorem.

x² = 58² - 40² = 1764

x = √1764 = 42

Find the 53rd term of the arithmetic sequence<br> 27,11, -5

vivado [14]

Answer:

The 53rd term of this arithmetic sequence is -805.

Step-by-step explanation:

The general rule of an arithmetic sequence is the following:

$a_{n+1} = a_{n} + d$

In which d is the common diference between each term, that is, $d = a_{3} - a_{2} = a_{2} - a_{1}$ .

To find the nth term of the sequence, this equation can be written as:

$a_{n} = a_{1} + (n-1)d$

27,11, -5

So $a_{1} = 27, a_{2} - a_{1} = 11 - 27 = -16[/tex[tex]a_{n} = a_{1} + (n-1)d$

$a_{53} = a_{1} + (52)d = 27 + 52*(-16) = -805$

The 53rd term of this arithmetic sequence is -805.
