Answer:
Step-by-step explanation:
Since two sides of the triangle are equal in length, we can conclude that 
is an isosceles triangle. With this information, we can draw an isosceles triangle to find 
. Since the base angles of an isosceles triangle are equal, we can solve for :
(Angle sum of triangle is 
)
(Base angles of isosceles triangles are equal, there is an image attached to show that is one of the base angles)
Hope this helps :)
See the attached figure.
<span>ad is a diameter of the circle with center p
</span>
∵ pd = radius = 7 ⇒⇒⇒ ∴ ad = 2 * radius = 2 * 7 = 14
∵ ae = 4 ⇒⇒⇒ ∴ ed = ad - ae = 14 - 4 = 10
∵ ad is a diameter
Δ acd is a triangle drawn in a half circle
∴ Δ acd is a right triangle at c
∵ bc ⊥ ad at point e
By applying euclid's theorem inside Δ acd
∴ ce² = ae * ed
∴ ce² = 4 * 10 = 40
∴ ce = √40 = 2√10 ≈ 6.325

Step-by-step explanation:
The density curve must satisfy two important conditions.
These two conditions are:
1- The total area under the density curve MUST BE equal to 1.
(Area total = 1)
2- Every point that is on the curve must have a vertical height that is equal to or greater than zero
(vertical height for each point ≥ zero)<span>

Number one is but number two is not
of more than 1 dot is on an “up and down” line then it’s not a function
