Answer:
The lamppost is 30 ft tall.
Step-by-step explanation:
You need to draw a diagram of the problem. Refer to attachment.
Now you need to convert the measurements that are in feet to in. The 1 foot ruler is now 12 in. and the 5 foot post's shadow is now 60 in.
The next step is to create a proportion between both angles.
x over 1 is simplified to x and 60 divided by 2 is just 30. So the lamppost is 30 ft tall.
Hope that helped. :)
Answer:
(1)55.5 feet
(2)7.5 feet
Step-by-step explanation:
<u>Question 1</u>
The diagram is attached below.
Using Trigonometric ratio
The height of the house is 55.5 feet to the nearest tenth.
<u>Question 2</u>
In the diagram, we are required to find the distance the bird must fly to be directly above the fish. This has been represented by x.
Using Trigonometric ratio
The distance the bird must fly to be directly above the fish is 7.5 feet.
Answer:
Step-by-step explanation:
We will use the general area formula for finding the area of triangle when you are given information for SAS, which we have been.
, where a and b are the given side lengths and C is the included angle. You can ONLY use this when you have the info for SAS in a triangle. For us,
a = 17, b = 15 and C = 35 degrees. Filling in:
Do that on your calculator in degree mode and you'll find the area to be
73.1 meters squared
