Answer:
x =
Step-by-step explanation:
r + s = 70 feet
Applying Pythagoras theorem to the triangle formed by cable r;
= +
= +
= 400 + 64
= 464
r =
= 21.541
Length of cable r is 21.54 feet.
So that,
r + s = 70 feet
21.54 feet + s = 70 feet
s = 70 feet - 21.54 feet
= 48.46 feet
Length of cable s is 48.46 feet.
Applying trigonometric function to the triangle formed by cable s, we have;
Sin θ =
Sin x =
= 0.4127
x = 0.4127
= 24.3746
x =
The measure of angle that s makes with the ground is approximately .
Answer:

Step-by-step explanation:
Given
Required
Determine the %decrease
First, we need to determine the amount paid
The percentage decrease is the calculated as follows:
In this case;
So; we have:
<em></em><em> (Approximated)</em>
Step-by-step explanation:
We need to find a midpoint. A midpoint splits the two end coordinates to meet at a point.
Use midpoint formula
So the coordinates will be at
(4,-5)
The coefficient of y∧15×∧2 in expansion of (y∧3+x)∧7 is (15×2)+(3×7)= 51
x-32.2= 18.5
Add 32.2 to both sides
x-32.2+32.2 = 18.5 + 32.2
x = 50.7
I hope that's help !
Check your answer
replace x by its number
50.7-32.2= 18.5
18.5 = 18.5
so the answer is good .
