Answer:
x = √70
Step-by-step explanation:
The right triangles are all similar, so we can write the ratio of long side to hypotenuse as ...
x/(7+3) = 7/x
x^2 = 7(10) = 70
x = √70
_____
Additional comments
This is called a "geometric mean", where x is the square root of the product of two numbers, 7 and 10. Those happen to be the lengths of the adjacent segment of the hypotenuse and the whole hypotenuse.
The same relation holds for BC:
BC = √(CD·CA)
__
A slightly different geometric mean relation holds for the altitude BD:
BD = √(DC·DA)

B) 5
C) 6
D) 12
Answers
Answer:
The value of x = 12, makes the statement [tex]3x=2x+12[/tex] true
Option D is correct option.
Step-by-step explanation:
What value of x makes this statement true?
[tex]3x=2x+12[/tex]
We need to solve the equation to find value of x
[tex]3x=2x+12[/tex]
Subtract 2x on both sides
[tex]3x-2x=2x+12-2x\\x=12[/tex]
So, the value of x is: x=12
So, The value of x = 12, makes the statement [tex]3x=2x+12[/tex] true
Option D is correct option.

Answer:
RS = 47 units
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
3x + 5 = [tex]\frac{1}{2}[/tex] ( 2x + 15 + 6x - 37)
3x + 5 = [tex]\frac{1}{2}[/tex] (8x - 22) = 4x - 11 ( subtract 4x from both sides )
- x + 5 = - 11 ( subtract 5 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16
Thus
RS = 2x + 15 = 2(16) + 15 = 32 + 15 = 47

Mr. JB has a rectangular lot that measures 550 meters by 550 km. What is the area of the land in square meter. He i selling the whole lot for 206,250,000 pesos how much is the price per square meter?
Answers
9514 1404 393
Answer:
15/22 peso/m^2 ≈ 0.68182 peso/m^2
Step-by-step explanation:
The area is the product of the dimensions. 1 km = 1000 m.
A = (550 m)(550·1000 m) = 302,500,000 m^2
The price per square meter is ...
206,250,000/302,500,000 peso/m^2
= 15/22 peso/m^2 ≈ 0.68182 peso/m^2
