Question

49. Calculate the value of c in the triangle below.

Answer 1

26m.

Explanation:

since the triangle has a 90° angle, it means that the triangle is a Right - angled triangle. So, we are going to use the pathagorean theorem to find the missing side.

a² + b² = c²

a and b are the two shorter and adjacent sides to the 90° angle

c is the hypotenuse

10² + 24² = c²

100 + 576 = c²

676 = c²

find the square root of 676 to get c = 26.

Answer 2

26 cm

Explanation:

c = a^2 + b^2 = 10^2 + 24^2 = 26
