Answer:
As per the statement:
You can see the diagram as shown below.
Distance of fireman stands away from the building = 30 m
Length of the ladder = 50 m
Using Cosine ratio:
....[1]
From the diagram:
Adjacent side = 30 m
Hypotenuse side = 50 m
Substitute these values in [1] to solve for angle of elevation(
)
or
Simplify:
Therefore, the angle of elevation to the closest degree of the ladder is 51.13 degree
Answer:
one answer
Step-by-step explanation:
set the equal to each other and you get one answer
2x+6= -3x -4
You can use Pythagoras theorem to find the radius.
r^2 + 8^2 = 10^2
r^2 + 64 = 100
r^2 = 36
r = 6
Answer: 299*100= 29,900
29,900/5.75= 5,200
answer is 5,200
Step-by-step explanation:
The slope-intercept form is
y
=
m
x
+
b
y
=
m
x
+
b
, where
m
m
is the slope and
b
b
is the y-intercept.
y
=
m
x
+
b
y
=
m
x
+
b
Find the values of
m
m
and
b
b
using the form
y
=
m
x
+
b
y
=
m
x
+
b
.
m
=
0.75
m
=
0.75
b
=
0.25
b
=
0.25
The slope of the line is the value of
m
m
, and the y-intercept is the value of
b
b
.
Slope:
0.75
0.75
Y-Intercept:
0.25
