There is no congruence between the triangles based on the given information. In general, two sides and an angle not between them are insufficient to specify the triangle completely. In this case, the angles that are congruent are adjacent to non-corresponding sides, so even if SSA correspondence were sufficient to ensure congruence, it would not be sufficient in this case.


The appropriate choice is

... none

Three less than three times a number is 5/6. What is one more than twice the number
dimaraw [331]

Answer:

32/9

Step-by-step explanation:

Translating the word problem into a symbolic equation yields:

3n - 3 = 5/6

Solve this for the number (n):

Multiplying both sides of this equation by 6 clears out the fraction term:

18n - 18 = 5

Adding 18 to both sides isolates 18n:    18n = 23

Then the number is n = 23/18, and:

one more than twice this number n is 2(23/18) + 1, or:

46/18 + 18/18, or 64/18, or (reducing this result)

32/9

Graph A line goes through the point (6,–2) and has a slope of –3. What is the value of a if the point (a,7) lies on the line?
3241004551 [841]

Answer:

The value of a is 3

Step-by-step explanation:

First you have to make an equation based on the point and slope that you were given. The formula for this is y-(y cordinate of point)=slope(x-x cordinate of slope)

y--2=-3(x-6), which simplifies to y+2=-3(x-6)

In (a,7), 7 is the y coordinate. We have to plug 7 in for the y in our equation.

7+2=-3(x-6),

Combine like terms on the left side to get to 9=-3(x-6)

Multiply out on the left to get 9=-3x+18

Subtract 18 from the left side to get -9=-3x

Divide both sides by negative 3 to get 3=x (remember x is a)
