What is the value of x to the nearest degree?<br><br> 48 <br> 42 <br> 84 <br> 24

Cerrena [4.2K]

Answer:

The value of the angle x is 48°.

Step-by-step explanation:

Base of the triangle = 10

Height of the triangle = 11

$\tanx =\frac{Height}{Base}$

$\tanx =\frac{11}{10}=1.1$

$x =\tan^{-1}1.1=47.7263^o\approx 48^o$

The value of the angle x to the nearest degree is 48°.

Georgia has a budget of $8 for a new notebook. She wants to spend within $5 of her budget, so she uses the equation 5 = |8 – x|

siniylev [52]

Answer:

Minimum: 3

Maximum: 13

Step-by-step explanation:

Georgia uses the equation

5 = |8 – x| to find the maximum and minimum values.

We solve the equation for x.

$5 = |8 - x|$

By the definition of the absolute value function, we must have:

$- 5 = 8 - x \: or \: 5 = 8 - x$

We subtract 8 from both sides to get:

$- 5 - 8 = - x \: or \: 5 - 8 = - x$

$- 13 = - x \: or \: - 3 = - x$

This simplifies to:

$13 = x \: or \: 3 = x$

Therefore the minimum value is 3 and maximum is 13
