(PT)^2 = PA . PB
PA = 15 + x
x = Diameter

-> 31^2 = (15 + x) . 15
-> 961 = 225 + 15 x
-> 15x = 961 - 225
-> 15x = 736
-> x = 736/15
-> x = approximadately 49

Answer: 1st Option (49.1)

The diameter is about 49.1
You can find this using the equation: 31^2 = 15 x (15+diameter)

Hope this helped!!

Answer:

x = 7

Step-by-step explanation:

The angle adjacent to the 70 degree angle is also 70 degrees.  We assume that there are four 90-degree angles in the center of the figure.  Thus, 8x - 36 + 70 + 90 = 180 (the sum of the interior angles is 180 degrees).

Solving  8x - 36 + 70 + 90 = 180 for x:

              8x - 36 = 20, or 8x = 56.

Dividing both sides by 8 yields x = 7.

The figure below was made with a scale of 1 unit =9 m. You can place your figure anywhere on the grid on the right.
Zielflug [23.3K]

Answer & Step-by-step explanation:

I can't draw the image, but I can explain it to you.

Since 1 unit was 3 units and now it's 9, you would have to divide each side by 3. So, the width would be 1 unit and the length would be 2 units.

I hope this helped!!!

If LM=41-2x and NP=7x+5, find LM
Tatiana [17]
Answer:
LM = 33 units

Explanation:
From the drawing:
LM = NP
41 - 2x = 7x + 5
41 - 5 = 7x + 2x
36 = 9x
x = 9

This means that:
LM = 41 - 2x 
LM = 41 - 2(4) 
LM = 33 units

Hope this helps :)

Answer:

They went up 16 levels.

Step-by-step explanation:

You can find that by finding the distance from -2 to 14.
To find the distance from two numbers, a and b, we can substitute both in the formula d = |b - a|, where d is the distance between them.

d = |14 - (-2)| \to |14 + 2|\to|16|\to16
