Answer:
(x + 2)² + (y - 4)² = 16
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 2, 4 ) and r = 4 , then
(x - (- 2))² + (y - 4)² = 4² , that is
(x + 2)² + (y - 4)² = 16
Answer:
The Height of the cliff is 41.5 meters tall.
Option B. 41.5 meters.
Step-by-step explanation:
Given:
AB = 85 meter
Angle of elevation ∠ C= 26°
To Find:
Cliff height = AB = ?
Solution:
In right angle Triangle ABC by tangent Identity we have

Substituting the given values we get


The Height of the cliff is 41.5 meters tall.
Answer:
Hey there,
Let the angle ABC = x
Let the angle CBE = y
Let the angle EBD = z
We want to find x.
So, we are given the following:
x+y+z=85
z=21
And y=z
therefore, both y and z must equal 21.
21+21=42
85-42=43.
By Pytogaros' Theorem,(however you spell it)

Let the length of shorter leg be x.So the longer leg will be x+2

so you end up with
0=2x^2+4x-96
Solve for x which gives you -8 and 6. So the shorter leg has length of 6 and longer leg has length of 8
