Angle sum property = Sum of the three angles of a triangle will be equal to 180° .

Using this let us find out the measure of x .

Measure of first angle = 101°

Measure of second angle = 38°

Measure of third angle = x

101 + 38 + x = 180

139 + x = 180

x = 180 - 139

= x = 41

∴ \: the \: value \: of \: x \:  = 41°

Eli attended a concert. The decibel level of the music averaged 110 decibels but varied by 28 decibels from the average. Enter a
musickatia [10]

Answer:

The decibel range is   82\leq d\leq 138

Step-by-step explanation:

Let

d -----> the decibel level of the music

we know that

The absolute value of the difference of the decibel level of the music and its average, must be less than or equal to 28 decibels

so

The absolute value that represent this problem is

\left|d-110\right|\le28

Solve the absolute value

<em>First solution (positive)</em>

+(d-110)\le28

Adds 110 both sides

d\le28+110

d\le138

<em>Second solution (negative)</em>

-(d-110)\le28

Multiply by -1 both sides

(d-110)\ge-28

Adds 110 both sides

d\ge-28+110

d\ge82

therefore

The decibel range is

82\leq d\leq 138

Which of the following is an extraneous solution of √4x+41 = x+5?
dolphi86 [110]

Answer:

x=-8

Step-by-step explanation:

on squaring both sides

either x-2=0  or  x+8=0

either x=2 or x=-8

Putting x=2 in original equation, we get

7=7 hence, it is not an extraneous solution

Putting x=-8 in original equation

i.e. 3=-3

Hence, x=-8 is an extraneous solution (since it doesn't satisfy the original equation)

Try This question solve using substitution I’ll give you brainliest
Semmy [17]

Answer:

(-4, -3)

Step-by-step explanation:

First divide the second equation by -1. It becomes y = -3x - 15.

Then, substitute this equation into the y of the first equation.

x + 2(-3x - 15) = -10

x - 6x - 30 = -10

-5x = 20

x = -4

Then substitute the x value into the equation x + 2y = -10

-4 + 2y = -10

2y = -6

y = -3
