Question

Mathematics: Which is an example of the associative property? (–8 + 10) + 4 = –8 + (10 + 4) –17 + 0 = –17 –5 + 7 = 7 + (–5) –(18 + 3) = –18 + (–3)

The height of the kite off the ground is 155.562 feet

Step-by-step explanation:

Given

Length = 220ft

$Angle = 45 \deg$

Required

Determine the height the kite is from the ground

This question is best explained with the following attachment

From the attachment, we have that the illustration of the question forms a right angled triangle triangle and required to solve for h

The relationship between h, 220 and 45 degrees is:

$Sin\ \theta = \frac{Opposite}{Hypothenuse}$

Where

$\theta = 45 \deg$

Opposite = h

Hypothenuse = 220

So, we have:

$Sin\ 45 = \frac{h}{220}$

Multiply both sides by 220

$h = 220 * sin\ 45$

h = 220 * 0.7071

h = 155.562

Hence, the height of the kite off the ground is 155.562 feet

Which is an example of the associative property?
(–8 + 10) + 4 = –8 + (10 + 4)
–17 + 0 = –17
–5 + 7 = 7 + (–5)
–(18 + 3) = –18 + (–3)
