What is the measure of angle C?<br><br> A 28°<br><br> B 62°<br><br> C 90°<br><br> D. 10°
Ray Of Light [21]

For this case we have that by definition, the sum of the internal angles of a triangle is 180 degrees. So, we have:

(5x + 12) + (6x + 30) + (2x + 8) = 180\\5x + 12 + 6x + 30 + 2x + 8 = 180

We add similar terms:

13x + 50 = 180\\13x = 180-50\\13x = 130\\x = \frac {130} {13}\\x = 10

Answer:

x = 10

Option D

What is the area of a rectangle if 1 base is 14 in, the 2nd base is 3.5 in and the height is 8 in?​
algol13

Check the picture below.

notice, we have three pair of sides, let's add them all up to get the area

\stackrel{\textit{left and right}}{2(8\cdot 14)}+\stackrel{\textit{front and back}}{2(3.5\cdot 8)}+\stackrel{\textit{top and bottom}}{2(3.5\cdot 14)}\implies 378~in^2

( – 1, – 5) 7x+2y=13, 4x+4y=14
serious [3.7K]

Answer:

{x,y} = {6/5,23/10}

Step-by-step explanation:

 [1]    7x + 2y = 13

  [2]    4x + 4y = 14  <---------- linear equations given

Graphic Representation of the Equations : PICTURE
2y + 7x = 13        4y + 4x = 14  

Solve by Substitution :

// Solve equation [2] for the variable  y

[2]    4y = -4x + 14

[2]    y = -x + 7/2

// Plug this in for variable  y  in equation [1]

  [1]    7x + 2•(-x +7/2) = 13

  [1]    5x = 6

// Solve equation [1] for the variable  x

  [1]    5x = 6

  [1]    x = 6/5

// By now we know this much :

   x = 6/5

   y = -x+7/2

// Use the  x  value to solve for  y

   y = -(6/5)+7/2 = 23/10

// Plug this in for variable  y  in equation [1]

 [1]    7x + 2•(-x +7/2) = 13

  [1]    5x = 6

// Solve equation [1] for the variable  x

 [1]    5x = 6

[1]    x = 6/5

// By now we know this much :

   x = 6/5

   y = -x+7/2

// Use the  x  value to solve for  y

  y = -(6/5)+7/2 = 23/10
