Answer:
Option D. 10,779 feet
Step-by-step explanation:
Given from the figure attached,
PT = OB = 7000 ft
PB = OT = x feet
and angle of elevation (∠POT) = 30°
By applying Tan rule in the triangle POT,
tan33° =
= 
tan33° = 
x = 
x = 10779 feet
Therefore, distance between the bird (B) and plane (P) is 10,779 feet.
Option D. will be the answer.
Answer:What are Whole Number? ... 17, 99, 267, 8107 and 999999999 are examples of whole numbers. Whole numbers include natural numbers that begin from 1 onwards. Whole numbers include positive integers along with 0.
Step-by-step explanation:
Answer:
3.491
Step-by-step explanation:
move the decimal over 3 places.
we know that
The <u>Triangle Inequality Theorem,</u> states that the sum of the lengths of any two sides of the triangle is greater than the length of the third side
so

we have

substitute the values
----->
-----> 
-----> 

therefore
<u>the answer is</u>
The value of x must be greater than 
The value of x and y in the equation -5x + 8y = -21 and 3x - 4y = 15 are 9 and 4 respectively.
<h3>What is an equation?</h3>
An equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario. It is vital to note that an equation is a mathematical statement which is made up of two expressions that are connected by an equal sign.
The equation is given as:
-5x + 8y = -21
3x - 4y = 15
Multiply equation i by 3
Multiply equation ii by 5
-15x + 24y = -63
15x - 20y = 75
Add both equations
4y = 12
Divide
y = 12/4
y = 3
From 3x - 4y = 15
3x - 4(3) = 15
3x - 12 = 15
Collect like terms
3x = 12 + 15
3x = 27
Divide
x = 27/3
x = 9
Therefore, x = 9 and y = 4.
