Answer:
4.9 feet
Step-by-step explanation:
First, we need to determine the height of the building using the following:
Where
H = Height of the building
L = Length of the first ladder = 20ft
B = Distance from the base of the building = 10ft
So, we have:
Next, is to determine the distance of the new ladder from the base of the building (B) using Pythagoras theorem using:
Where
--- Length of the second ladder
----- Height of the building
So, we have:
Solving for B2, we have:
<span>Let opposite ray be drawn for the base side ray of the given angle.
This gives angle 180° between these two rays.
Angle bisectors of the given angles 50°, 90°, and 150° make respectively half of these angles : 25° , 45° and 75° with the base ray.
Then measure of the angles between the bisectors of the given angles and the drawn opposite ray are 180°-25°=155°, 180°- 45° =135° and 180°- 75° = 105° respectively.</span>
Answer:
D. 6
Step-by-step explanation:
the similarity theorem:
x/9 = 8/12
12x=8 (9)
12x = 72
x = 72/12
x = 6
Answer:
Rational!
Step-by-step explanation:
The decimal is terminating so this is rational.
Answer:
$2.16 per pound
Step-by-step explanation:
First, you would need to divide the price by the amount
$12.96 / 6 lbs = $2.16 per pound
That is the unit price
