To find : Write a variable expression the algebraic expression ?
Solution :
A variable is defined as the symbol for a number we don't know yet.
It is usually a letter like x or y.
1)
The variable in the expression is unknown value i.e. x.
2)
The variable in the expression is unknown value i.e. x.
3)
The variable in the expression is unknown value i.e. x.
4)

Answer:
219m
Step-by-step explanation:
Since the man observes the car with angle 15 before observing in 33 degrees.
For the first observation
The angle observation gives an angle if 33 degrees with the horizontal.
It gives a triangle which I'll attach to the que,
from the first triangle
Tan 33 = 100/y
Y= 100/ tan 33
Y = 153.99m.
This is the distance from the building to the distance where it was secondly observed( 33).
To find x
tan 15 = 100/(153.99+x)
153.99 + x = 100/ tan 15
153.99 + x = 373.21
The distance between the two observed angles
X= 219m.
Answer:
4000
Step-by-step explanation:
V = 1/3(Bh) where B is the area of the base and h is the height of the pyramid
B = 20(20) = 400 h = 30
V = 1/3(400)(30) = 4000
