What's the length of side AB in ∆ABC shown? <br>A. 5 <br>B. √313 <br>C. 6 <br>D. √15​
HACTEHA [7]

Answer:

The value of x = 5 units.

Step-by-step explanation:

Given the right-angled triangle ∆ABC with the following dimensions

AC = a = 12

BC = c = hypotenuse = 13

AB = b = x

Pythagorean Theorem

For a right-angled triangle with the sides, a and b the hypotenuse c is defined as:

c=\sqrt{a^2+b^2}

Thus, using the Pythagorean Theorem to determine the value 'x',

b=\sqrt{c^2-a^2}

as b = x, so

x=\sqrt{c^2-a^2}

  • a = 12
  • c = 13

so

x=\sqrt{13^2-12^2}

x=5

Therefore, the value of x = 5 units.

Two​ trains, Train A and Train​ B, weigh a total of 300 tons. Train A is heavier than Train B. The difference of their weights i
eduard

Answer:

Train A = 214

Train B = 86

Step-by-step explanation:

a + b = 300

a - b = 128

a + b = 300

a = 128 + b

(128 + b) + b = 300

128 + b + b = 300

128 + 2b = 300

2b = 300 - 128

2b = 172

b = 172 ÷ 2

b = 86

a = 128 + b

a = 128 + (86)

a = 214

Use the table to find the COORDINATES of the image ​
Natasha_Volkova [10]

Answer:

Q = ( -3 , 6 ) .... R = ( -1 , 8 )  ...... S = ( -5 , 7 )

Step-by-step explanation:

Q = ( 1 + ( -4 ) , 4 + 2 ) = ( -3 , 6 )

R = ( 3 + ( -4 ) , 6 + 2 ) = ( -1 , 8 )

S = ( -1 + ( -4 ) , 5 + 2 ) = ( -5 , 7 )
