Answer: 150
We know that cos Ф = sin (90 - Ф)
If Ф = 150, then:
cos 150 = sin (150 - 90)
cos 150 = sin 60
Using the equation they gave us:
cos 150 = sin ( - 10)
cos 150 = sin 60

Answer:
Height of the object is 68.6 cm.
Step-by-step explanation:
The height of the object can be determined by:
=
From the given question;
object distance from pinhole = 3.6 m = 360 cm
image distance from pinhole = 4.2 cm
height of image = 0.8 cm
So that;
=
⇒ object height =
=
= 68.571
object height = 68.6 cm
Thus, the height of the object is 68.6 cm.

Please see the attached pictures for full solution.
For the first question, the inequality sign is
because of the word "at least". This means that the profit can be greater or equal to $980.
2nd question part b: I saw your working on another post... you're almost there! After finding the circumference of the semi circle, add the diameter of the semicircle (2 radius) since it's part of the garden too.
For the 3rd question part b, I multiply 12.8 by 15 because we know that from part a that 1cm of the scale drawing represents 15 feet of the actual parking lot. Since the length of the parking lot on the scale drawing is given to be 12.8cm, the actual length is 12.8×15= 192 feet. (I answered this question on another post of yours but I decided to explain it again here)
