Answer:

B 84

Step-by-step explanation:

Angles P and R are complementary, so ...

(2x -6) + (3x -24) = 90

5x -30 = 90 . . . collect terms

x -6 = 18 . . . . . divide by 5

x = 24 . . . . . . . add 6

∠P = (2x-6)° = (2·24 -6)° = 42°

The measure of arc SR is twice the measure of ∠P, so is ...

arc SR = 2·42° = 84°

Find the coordinates of P ' if D o, 2.4 (x,y) is applied to the triangle below

guajiro [1.7K]

Answer:

The coordinates of P' are (4.8,-4.8).

Step-by-step explanation:

The rule of dilation $D_{o,2.4}(x,y)$ represent the dilation with scale factor 2.4 and center at origin.

If the scale factor of the dilation is k and the center is (0,0), then

$(x,y)\rightarrow (kx,ky)$

Since the scale factor is 2.4, therefore

$(x,y)\rightarrow (2.4x,2.4y)$

From the given figure it is noticed that the coordinates of P are (2,-2). The coordinates of P' are

$P(2,-2)\rightarrow P'(2.4(2),2.4(-2))$

$P(2,-2)\rightarrow P'(4.8,-4.8)$

Therefore the coordinates of P' are (4.8,-4.8).
