Answer:

110 degrees,

Step-by-step explanation:

The unmarked external angle = 180-109 = 71 degrees.

x = 360 - 63 - 66 - 50 - 71 = 110.

Answer:

x = 110°

Step-by-step explanation:

the sum of the exterior angles of a polygon = 360°

the exterior angle to 109° is

180° - 109° = 71° ( adjacent angles on a straight line )

then summing the exterior angles and equating to 360°

63° + 66° + 50° + x + 71° = 360° , that is

250° + x = 360° ( subtract 250° from both sides )

x = 110°

The solution to the equation log2x + log2(x – 6) = 4 is x =

GenaCL600 [577]

Answer:

Value of x=8

Step-by-step explanation:

Given : $log_2x+log_2(x-6)=4$

To find : The solution to the equation given

Solution :

Step 1- Write the given expression

$log_2x+log_2(x-6)=4$

Step 2 - Using logarithmic laws

$log_{b}x+log_by=log_bxy$

$log_2(x)(x-6)=4$

Step 3 - To remove log-base 2, we need to raise the left and right hand terms to power 2.

$(x)(x-6)=2^4$

$x^2-6x-16=0$

Step 4 - Solve the quadratic equation

$x^2-8x+2x-16=0$

$x(x-8)+2(x-8)=0$

$(x-8)(x+2)=0$

Either x=8 or x=-2

We neglect x=-2 because negative value is not defined in log.

Value of x=8
