Triangle ABC is congruent with triangle CDA Find the value of the pronumeral x.
brilliants [131]

Answer:

x = 25

Step-by-step explanation:

Since the triangles are congruent then corresponding angles are congruent.

That is ∠ D and ∠ B are corresponding angles and congruent, thus

4x - 20 = 2x + 30 ( subtract 2x from both sides )

2x - 20 = 30 ( add 20 to both sides )

2x = 50 ( divide both sides by 2 )

x = 25

How many solutions does the equation have?
Ratling [72]
3(4x - 3) - 7x = 5x - 9

First, expand your equation so it will be easier to simplify.
(3)(4x) + (3)(-3)+-7x = 5x + -9
Second, multiply (3)(4x) to get 12x. 
12x + (3)(-3)+-7x=5x + -9
Third, multiply (3)(-3) to get -9.
12x + -9 + -7x = 5x + -9
Fourth, combine the like terms. (x and -9 alone).
(12x + -7x) + (-9) = 5x - 9
Fifth, subtract (12x + -7x) to get 5x.
5x + -9 = 5x - 9
Sixth, change 5x + -9 into a subtraction.
5x - 9 = 5x - 9
Seventh, since both sides are equal, that means that the equation has infinite solutions.

Answer: B) infinite solutions
