In the given question, it is given that
ramp is 17 feet long, rises 8 feet above the floor, and covers a horizontal distance of 15 feet.
And we have to find the value of tan B.
And tangent of any angle is equal to the ratio of vertical by horizontal. That is
And that's the required missing ratio for tan B .
Answer:
The correct option is E. 8
The value of h is 8 unit.
Step-by-step explanation:
Given:
Δ BAD ~ Δ CBD
AC = 20
DC = 4
∴
To Find:
h = ?
Solution:
Δ BAD ~ Δ CBD ................Given
If two triangles are similar then their sides are in proportion.
On substituting the given values we get
The value of h is 8 unit.
Answer
Circumference(C) of a circle is given by:
where r is the radius and value of
As per the given statement:
A building engineer analyzes a concrete column with a circular cross section.
The circumference of the column is meters.
then;
Divide both sides by we have;
9 = r
or
r = 9 meters
We have to find the area of the cross section of the column
Area of a circle is given by:
then;
meter square.
therefore, the area A of the cross section of the column is meter square.
