Question

A right triangle has a hypotenuse of 32 cm and a base measurement of 8 cm. What is the length of its altitude leg to the nearest whole number?
1. 31 cm

2. 34 cm

3. 30 cm

4. 38 cm

Answer 1

Answer:

1. 31

Step-by-step explanation:

a² + 8² = 32² (figure out what 8² and 32² equal)

a² + 64 = 1024 (subtract 1024 - 64)

a² = 960 (find the square root of 960)

√960 = 30.98 = 31  (round to the nearest whole number)
