Find The Missing Length Of The Triangle class=

Sagot :

Answer:

29 = c

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

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

20^2 + 21^2 = c^2

400 +441 =c^2

841 = c^2

Take the square root of each side

sqrt(841) = sqrt(c^2)

29 = c

Answer:

c = 29 km

Step-by-step explanation:

21² + 20² = c²

441 + 400 = 841

√841 = 29
