Answer:
x = 45
Step-by-step explanation:
The 3 angles of a triangle add up to 180
<a + <b + <c = 180
substitute what you know
55+ 80 + <c = 180
combine like terms
135 + <c = 180
subtract 135 from each side
<c = 180 -135
<c = 45
x = 45
The ratio of largest to smallest share is 9:3, so that the largest share is 3 times that of the smallest share. If the largest share is 54, 54/3=18.

Answer:
548
Step-by-step explanation:
First, the sides:
7 × 12 = 84
84 × 2 = 168
7 × 10 = 70
70 × 2 = 140
10 × 12 = 120
120 × 2 = 240
Add:
168 + 140 + 240
^ ^
308 + 240
548
Hope this helped.
The missing numerator that will make the rational expressions equivalent is (82x + 7) / (12x + 42)
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let y represent the missing numerator, hence:
82x + 7 = y * 6(2x+7)
82x + 7 = y * (12x + 42)
y = (82x + 7) / (12x + 42)

Answer:
Part 1) 
Part 2) 
Part 3) The coordinates of endpoint C are (13,5)
Step-by-step explanation:
Part 1) The endpoints of line RS are R(1, -3) and S(4,2). Find RS
we now that
the formula to calculate the distance between two points is equal to

substitute the values



Part 2) The endpoints of line CD are C(-8,-1) and D(2,4). Find CD
we now that
the formula to calculate the distance between two points is equal to

substitute the values



Part 3) The midpoint of line AC is M(5,6). One endpoint is A(-3,7). Find the coordinates of endpoint C
The formula to calculate the midpoint between two points is equal to

Let
(x2,y2)-------> the coordinates of point C
(x1,y1) -------> the coordinates of point A
substitute the given values

write the equations


therefore
The coordinates of endpoint C are (13,5)
