Answer:

Step-by-step explanation:

You have to assume that P is the center of the circle. Without that fact, there is no answer.

Both PT and PB are radii. Therefore the triangle containing <PTB and <PBT is isosceles. What that means is that angle PTB = angle PBT

So angle PBT is the answer.

Answer:

x=125

Step-by-step explanation:

∠PAT=180° - ∠ATP - ∠APT

∠PAT=180 - 3x - 3 -4x -4= (173 - 7x)°

3x + 3 + 4x + 4 + 173-7x = 180

⇔x = 125

The actual length (L) of a rectangle is 27 centimeters. Use the scale drawing of the rectangle to find the actual width (W).

Dominik [7]

The ratio of the length to the width is $\rm \dfrac{L}{W}$ .
The ratio of the sides will be the same for the scale and actual figures.

$\rm \dfrac{2.4}{3.6}=\dfrac{27}{W}$

I took the L/W of the scale figure
and set it equal to the L/W of the actual figure.

Now we can solve for the unknown width.
Cross-multiplication gives us this,

$\rm 2.4W=3.6\cdot27$

Divide by 2.4 and simplify,

$\rm W=40.5$

Hope that helps! :)

ΔABC is dilated by a scale factor of 0.25 with the origin as the center of dilation, resulting in the image ΔA′B′C′. If A = (-1,

Answer:

c. d = 5

Step-by-step explanation:

The difference in coordinates B and C is (14, 17) -(2, 1) = (12, 16). When the figure is scaled by 0.25, that difference becomes ...

0.25(12, 16) = (3, 4)

The length of a line segment with those coordinate differences is ...

d = √(3² +4²) = √25 = 5 . . . . matches selection c.

How do you solve P=3r+2s; for s?

EastWind [94]

P = 3r + 2s --> P - 3r = 3r - 3r + 2s
2s = P - 3r --> 2s/2 = (P - 3r)/2
s = (P - 3r)/2
