Answer:

(16, -23)

Step-by-step explanation:

We assume your notation means the figure is dilated by a factor of 3 with the origin as the center of dilation, then it is translated 2 units left and 4 units up.

These transformations can be written as ...

(x, y) ⇒ (3x, 3y) . . . . . . . dilation by a factor of 3 about the origin

(x, y) ⇒ (x -2, y +4) . . . . translation by (-2, 4)

These two transformations together give you ...

(x, y) ⇒ (3x -2, 3y +4)

(6, -9) ⇒ (3·6 -2, 3(-9) +4) = (18 -2, -27 +4) = (16, -23)

The point is transformed to (16, -23).

Answer: B) 16 units

Step-by-Step Explanation:

As we can observe from the graph,

Length (l) = 5 units
Breadth (b) = 3 units

Perimeter = 2(l + b)

Therefore,
= 2(l + b)
= 2(5 + 3)
= 2(8)
= 2 * 8
=> 16

Perimeter = 16 units

In ΔABC, ∠A measures 132° and the values of b and a are 36 and 70, respectively. Find the remaining measurements of the triangle

Amanda [17]

Answer:

Step-by-step explanation:

You have an angle and 2 sides given. It just so happens that the angle is across from one of the sides. We can use the Law of Sines to find the missing angle B first.

$\frac{sin(132)}{70} =\frac{sinB}{36}$

and cross multiply to get

36 sin(132) = 70 sinB and

$\frac{36sin(132)}{70} =sinB$ and

sinB=.3821887674

In order to find a missing angle you will use the 2nd button on your calculator along with the sin button. When you do that you will see

$sin^{-1}($ and then enter the decimal and hit "enter". You will get that the missing angle B measures 22.5 rounded to the nearest tenth.

Now that you have angles A and B, you can find C using the Triangle Angle-Sum Theorem (that says that all the angles of a triangle have to add up to equal 180).

C = 180 - 132 - 22.5 so

C = 25.5 degrees

Now we can use the Law of Sines again with angle A and side A and angle C:

$\frac{sin(132)}{70} =\frac{sin(25.5)}{c}$ and
