Answer:
(4√3)/3
Step-by-step explanation:
You know the ratio of side lengths is ...
x : 4 = 1 : √3
Then ...
x = 4/√3
Multiply by (√3)/(√3) to rationalize the denominator:
x = (4√3)/3
Answer: He accidentally mixed up the numbers, he should've described his movement with 7+(-9)
Step-by-step explanation:
For this case, we can model the problem as a rectangle triangle.
We know the height of the triangle.
We know the angle between the base of the triangle and the hypotenuse.
We want to find the base of the triangle.
For this, we use the following trigonometric relationship:
tan (70) = 39 / x
Clearing x we have:
x = 39 / tan (70)
x = 14.2 feet
Answer:
The distance between the base of the building and the base of the ladder is:
x = 14.2 feet
The left side is a half circle.
The area of a circle is PI x r^2
The diameter of the circle would be the height of the rectangle, given as 10 feet.
The radius is 1/2 the diameter, so 5 feet.
The area of half the circle is (3.14 x 5^2) / 2 = 39.25 square feet.
The area of the rectangle is 20 x 10 = 200 square feet.
Total area = 200 + 39.25 = 239.25 square feet.
Answer: 13/7
Step-by-step explanation: So you add a one on the bottom of the 5 then multiply it. 5X3=13 and 1X7= 7 then you get 13/7.
