Question

A right-angled triangle has one side of length 1.5 cm. Its hypotenuse is 6 cm. How long is its other side?

Answer 1

Answer:

Step-by-step explanation:

pythagorean theorem. a^2+b^2=c^2

1.5^2+b^2=6^2

2.25+b^2=12

12-2.25=b^2

b^2=9.75

take the square root

b=3.12

Answer 2

Answer: b = 5.809

Explanation:

Use Pythagorean’s Theorem

a^2 + b^2 = c^2 => b^2 = c^2 - a^2

b^2 = 6^2 - 1.5^2
b^2 = 36 - 2.25
b^2 = 33.75
b = sqrt(33.75)
b = 5.809
