Answer:

x =6.0

The base is 6x  = 35.8

The side is 3x =  17.9

Step-by-step explanation:

We can use the pythagorean theorem

a^2 + b^2 = c^2

(6x)^2 +(3x)^2 = 40^2

36x^2 + 9x^2 = 1600

Combine like terms

45x^2 = 1600

Divide each side by 45

45x^2 /45 =1600/45

x^2 =35.555555555

Take the square root of each side

sqrt(x^2) = sqrt(35.555555555)

x =5.96284794 = 6.0

The base is 6x = 6*5.9628479 =35.77708 = 35.8

The side is 3x = 3*5.9628479 =17.88854382= 17.9

Answer:

x = 6.0

3x = 17.9

6x = 35.8

Step-by-step explanation:

Using pythagoras theorem

40² = (3x)² + (6x)²

1600 = 9x² + 36x²

1600 = 45x²

x² = 320/9

x = 5.96284794

3x = 17.88854382

6x = 35.77708764

Find the distance between the points (2, -3) and (5, -4)
neonofarm [45]
D = sqrt (x2 - x1)^2 + (y2 - y1)^2
(2,-3)...x1 = 2 and y1 = -3
(5,-4)...x2 = 5 and y2 = -4
now we sub and solve
d = sqrt (5 - 2)^2 + (-4 - (-3)^2)
d = sqrt (3^2 + (-1^2)
d = sqrt (9 + 1)
d = sqrt 10
d = 3.16 <==
