Answer:

C. x = 72 degrees.

Step-by-step explanation:

The 2 marked angles are alternate angles between 2 parallel lines so they are congruent. Thus:

x - 20 = 52

x = 52 + 20

x = 72 degrees.

PtichkaEL [24]
Yes; a triangle is formed:
<span>______________________________________________________</span>
m∡A = 17° ;
m∡B = 137° (given) ;
m∡C = 26° ;
   a = 6 ;
   b = 14 (given) ;
   c = 9 (given) .
______________________________________________________
Explanation:
______________________________________________________
Note:

The law of sines:

(sin A) / a = (sin B) / b = (sin C) / c ;
______________________________________________________
Given: 
______________________________________________________
B = 137 ;
c = 9 ;
b =14 ;
______________________________________________________
 (sin B) / b = (sin C) / c ;
                
 (sin 137) / 14 = (sin C) / 9  ;

 (0.681998360062) / 14 = 0.0487141685758571 = (sin C) / 9  ;
______________________________________________________

sin C = (0.0487141685758571) * (9) ;

sin C =  0.4384275171827139 ;

        Take the "arc sin" of each side of the equation; to isolate "C" on one side of the equation; and to solve for "C" ;

arc sin (C) = arc sin ( 0.4384275171827139) ;

           C = 26.003593520741  ; round to 26.

If all angles of a triangle add up to 180 degrees: then:

A + B + C = 180 ;

A + 137 + 26  = 180 ;

A + 163 = 180 ;

Subtract "163" from each side of the equation; to isolate "A" on one side of the equation; and to solve for "A" ;

A + 163 − 163 = 180 − 163  ;

      A = 17 ;

Now, to solve for "a" ;

(sin A) / a = (sin B)/ b ;

(sin 17) / a = 0.0487141685758571 ;

(0.0487141685758571) a = (sin 17) ;

Divide EACH SIDE of the equation by:  "(0.0487141685758571)"  ;
______________________________________________________
           to isolate "a" on one side of the equation; and to solve for "a" ;
______________________________________________________
[(0.0487141685758571)a ] / (0.0487141685758571) = 

                   (sin 17) / (0.0487141685758571) ;
_________________________________________________________
                   a =  (sin 17) / (0.0487141685758571) ;

                      = (0.292371704723) / (0.0487141685758571) ;

                   a = 6.0017796314787227112 ;  round to "6" .

Define the words <br><br> please help
Brrunno [24]

Answer:

Irrational Number: A number that cannot be written as a fraction  

a

b

(where b ≠ 0), a repeating decimal, or a terminating decimal.

Rational Number: A number that can be written as a fraction  

a

b

(where b ≠ 0), a repeating decimal, or a terminating decimal.

Repeating Decimal: A decimal where, when dividing, a digit or group of digits repeats without end in the quotient; there is a pattern in the digits that repeat without end.

Terminating Decimal: A decimal that, when dividing, ends with a remainder of zero.

Perfect cube: A number that is made by cubing a number: a3 = a • a • a.

Perfect square: A number that is made by squaring a number: a2 = a • a.

Cube Root:

if a3 = b, then a = 3√b

For principal square root this was the best I could do: The principle of square roots requires that the square root of the side with the unknown (x) only includes x without any exponent (other than 1). The simplest form that fits this criterion is: but x can also be an expression.

I hope this helps :3

Answer:The answer is c

Step-by-step explanation:

Multiply both side is the equation by -1.

Sum the equations vertically to eliminate at least one variable

Divide both sides of the equation by 3

Substitute the given value of y into the equation 2x+3y=8

and then solve for x
