Answer:
Therefore the length of line Segment BC is 20.5 in.
Step-by-step explanation:
Given:
In Right Angle Triangle ABC
∠C = 90°
∠B = 35°
BC = a
AB = hypotenuse = 25
To Find:
BC = ?
Solution:
In Right Angle Triangle ABC , Using Cosine Identity we get
Substituting we get
Therefore the length of line Segment BC is 20.5 in.
We have that The height changing rate when the length of the base is 2 cm
From the question we are told
The diagonal of a rectangle, with base x, remains at a fixed value of 3cm. If the base is increasing at a rate of 8 cm/s. at what rate is the height changing when the length of the base is 2 cm?
Generally the Pythagoras equation for the triangle is mathematically given
as
With r=3
Therefore
dx/dt=8cm/s
Hence
We have
Therefore
The height changing rate when the length of the base is 2 cm
