Artemon [7]2 years ago
7 0

Answer:

Step-by-step explanation:

m∠ABC + m∠BAC + m∠ACB = 180°

a + 2a + 6a = 180°

9a = 180°

a = 20°

m∠ABC = 20°

m∠BAC = 2 × 20° = 40°

m∠ACB = 6 × 20° = 120°

Write an expression to represent: The sum of ten and the quotient of a number x and 6.
Minchanka [31]
Let us break it down. A sum of ten. That is just 

+10

Then, we will add that to the quotient (which is the number after dividing) of a number x and 6. We can write that as 

+ x/6

The slash means division here. Thus your final answer is 


10 + x/6

zlopas [31]

Answer:

Cross section

Step-by-step explanation:

Cross section refers to the new two dimensional face exposed when we slice through a three dimensional objects.

It can also be the surface or shape exposed by making a straight cut through something, especially at right angles to an axis.

Cross section is the plane surface(two-dimensional objects) formed by cutting across a solid shape (three-dimensional shape) especially perpendicular to its longest axis.

Alina [70]
X^2-2x -3 =0
a =1 b =-2 and c = -3 

x = - (-2) +/- sqrt (-2)^2 - 4(1)(-3)
      --------------------------------------
                   2(1)

 x = + 2 +/- sqrt [(4) - 4(-3)]
       -------------------------------
                    2

 x = +2 +/- sqrt [4 + 12]
       --------------------------
                   2
x = +2 +/- sqrt[16]
      -------------------
              2

x = +2 +/- (4)
      -------------
             2

x = 2 + 4    or 2 -4 
      -------        ------
         2               2

x = 6/2      or   -2/2

x = 3   or x = -1
