Answer 2

Answer

Explanation:

So, using the Pythagoras Theorem,

x²= 8² + (4√5)² = 64+80 = 144.

• So (x) = √144 = 12.

AC = 4 = CE.

AB = 5.

BD = 7.

AD = 12.

DE = 4√5.

• So, first let us find (P):

Cos(P) = Base/Hypotenuse = 8/12

= 2/3.

So, (P) = cos (2/3).

• Now, let us find (Q):

Tan(Q) = Perpendicular/Base = 8/ (4√5)

= 2/√5.

So, (Q) = tan (2/√5).

• Therefore, (P) = cos (2/3).

(Q) = tan (2/√5).

Now, let us find (BC) which can be taken out by Pythagoras Theorem.

BC = √AB² - AC².

√ 5² - 4².

√25 - 16.

√9.

√3.

• Therefore, (BC) = √3.
