A "system" of equations is a set or collection of equations that you deal with all together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables.

Answer:

$\sf adjacent = 4.5 \ ft$

Given:

opposite side: 13 ft
adjacent unknown
angle of 71°

using tan rule:

$\sf tan(x) = \dfrac{opposite}{adjacent}$

$\hookrightarrow \sf tan(71) = \dfrac{13}{adjacent}$

$\hookrightarrow \sf adjacent = \dfrac{13}{tan(71) }$

$\hookrightarrow \sf adjacent = 4.5$

If n denotes a number to the left of 0 on the number line such that the square of n is less than 1/100, then the reciprocal of n

andriy [413]

Answer: E. Greater than 10

Step-by-step explanation:

First, know that number to the left of a number line are negative and the square of any negative number will be positive and a perfect square.

Since the square of the unknown number is less than 1/100 i.e 0.01 then the possible unknown number 'n' can be -0.01 itself, of which the square of -0.01 will give us 0.0001 (1/10,000) i.e a value less than 0.01.

The reciprocal of 1/10000 is 10,000 which is a value greater than 10.
