Which transformations will produce similar, but not congruent, figures?

2 answers:

6 0

Dilations, rotations, and translations produce similar figures. Reflections don't,
because they produce mirror images, which may be similar in certain cases but
in general are not.

Choices 'B' and 'C' are the ones that don't involve reflections.

Answer:

$\dfrac{(a+b)}{ab}$

Step-by-step explanation:

The given expression is :

$\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}$

It can be solved as follows :

$\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}=\dfrac{a}{b(a-b)}+\dfrac{b}{a(b-a)}\\\\=\dfrac{a}{b(a-b)}+\dfrac{b}{-a(-b+a)}\\\\=\dfrac{1}{a-b}(\dfrac{a}{b}-\dfrac{b}{a})\\\\=\dfrac{a^2-b^2}{ab(a-b)}\\\\=\dfrac{(a-b)(a+b)}{ab(a-b)}\\\\=\dfrac{(a+b)}{ab}$

So, the solution of the given expression is equal to $\dfrac{(a+b)}{ab}$ .

sveticcg [70]

Answer:

<1 = 33 degrees

<2 = 33 degrees

<3 = 114 degrees

Step-by-step explanation:

<1 and <2 = x

<3 = 3x+15

<1 + <2 + <3 = 180 degree

x + x + 3x + 15 = 180

5x = 180 - 15

x = 165/5

x = 33

<3 = 3(33)+15

= 114 degrees

What is the tangent ratio for ∠A?

tiny-mole [99]

for this case we have to define trigonometric relations of rectangular triangles, that the tangent of an angle is given by the leg opposite the angle on the leg adjacent to the angle. So:

$tg (A) = \frac {6} {8} = \frac {3} {4}$

Answer:

$tg (A) = \frac {3} {4}$
