Question

.
Find the value of h in the parallelogram. Round your answer to the nearest tenth.

Answer 1

h ≈ 3.9

Explanation:

Using the right triangle with hypotenuse 4

Use Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

h² + 1² = 4²

h² + 1 = 16 ( subtract 1 from both sides )

h² = 15 ( take the square root of both sides )

h =
`√(15)` ≈ 3.9 ( to the nearest tenth )
