Answer:
option (c)
4√34
Explanation:
Given in the question is a right angle triangle
height of triangle = 20 cm
base of triangle = 12 cm
To find the length of missing side of the triangle we will use pythagorus theorem
hypotenuse² = height² + base²
hypotenuse² = 20² + 12²
hypotenuse² = 400 + 144
hypotenuse² = 544
take square root on both sides
√hypotenuse² = √544
hypotenuse = 4√34 cm
Hence, the length of missing side of the triangle is4√34 cm
