When writing the equation keep in mind that 7 + x is said as a term that is squared so it has to be squared while it's still together; (7 + x)².
First to answer
Answer:
x<7
Step By Step Answering:
Step 1: Simplify both sides of the inequality.
x+10<−4x+45
Step 2: Add 4x to both sides.
x+10+4x<−4x+45+4x
5x+10<45
Step 3: Subtract 10 from both sides.
5x+10−10<45−10
5x<35
Step 4: Divide both sides by 5.
5x/5<35/5
x<7

Step-by-step explanation:
The height of the tree given the depression angle to the top and the base
is given by the tangent relationship of the two given angles.
Correct response:
- The height of the tree is approximately <u>79.58 feet</u>
<h3 /><h3>Methods used for the calculation of the height of the tree</h3>
Given:
Altitude of the hot air balloon = 800 feet
Angle of depression to top of tree = 43°
Angle of depression to base of tree = 46°
Required:
Height of tree
Solution:
The horizontal distance of the balloon from the tree is given as follows;
Therefore;

Therefore;

- Height of tree = Altitude of balloon - Height of balloon above tree
Therefore;
