Question

Find the missing length of the triangle. If necessary, round your answer to the nearest tenth

Answer 1

Answer:

30

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem to find the missing side

a^2 +b^2 = c^2  where a and b are the sides and c is the hypotenuse

x^2 + 40^2 = 50^2

x^2 +1600 = 2500

x^2 = 2500-1600

x^2 = 900

Take the square root of each side

sqrt(x^2) = sqrt(900)

x = 30

Answer 2

Answer:

x = 30

Step-by-step explanation:

$a^{2} = c^{2} - b^{2}$

$a^{2} = 50^{2} - 40^{2}$

$a^{2} = 2500 - 1600$

$a^{2} = 900$

$\sqrt{a^{2}} = \sqrt{900}$

a = 30
