1 answer:
First, find the area of the rectangle. The formula is already given, and the length and width is shown on the 'beautiful drawing'.
The area of the rectangle is 171cm².
Find the area of the triangle. We see that it fits perfectly inside the triangle with some space to spare. It has the same height, so we have our 'h' value. Because there are 4cm and 3cm left for the width, subtract the sum of these numbers from the width.
, so the base of the triangle is 5cm long (remember that the figure isn't drawn to scale. I almost missed this one).
Final step. Subtract the area of the triangle from the rectangle: .
The area of the shaded region is 148.5cm².
Hope this was helpful.

Answer:
The missing height is approximately 78.8011 feet.
Step-by-step explanation:
To solve for the height of the kite, you need to use a trigonometry function called sine. Sine - or sin when used to calculate - is most commonly used for right triangles, and the sine of a right triangle angle is equivalent to the side opposite (or the only side of the right triangle that does not help create that angle) of the angle divided by the hypotenuse of the right triangle. So you can now create the following function to solve the height: sin(52°) = where x represents the unknown height of the kite. From there, you can get that
52°
, which equals approximately 78.8011 feet. Since there isn't a specific decimal place to round to, I rounded the answer to four decimals. If your teacher asks you to round to a specific place value, use 78.8011 to get your simplified answer.
