Question

a side of an isosceles right angle triangle is 7cm find its hypotenuse​

Answer 1

Answer:

9.8 cm.

Step-by-step explanation:

according to pythogoras to theorem

sq of hypotenuse = sum of sq of other two sides in right angle triangle.

side a = 7 cm

side b = 7cm ( isosceles triangle)

hypotenuse = ?

a² + b² = ç²

7² + 7² = c²

49 + 49 = c²

√98 = c

c= 9.899 cm

c= 9.8 cm
