Find 
In trigonometry,
If
, then

So, in this case:

Subtract 6 from both sides



<em>Hence, the value of </em>
<em> is 84 degrees</em>
Answer:
7) x= 5, 8) x= 6, 9) x= 7
Step-by-step explanation:
As per the secant theoram, if two secant intersect outside the circle then the product of the exterior secant and total length of each secant are equal.
7) ∴ 
opening parethesis and distributing 3 with x and 3.
⇒ 
subtracting 9 on both side.
⇒ 
cross multiplying
∴ x= 5.
8) 
Opening parethesis and distributing 4 with x and 4.
⇒ 
⇒ 
subtracting 16 on both side.
⇒ 
cross multiplying
∴ x= 6.
9) 
opening parethesis and distributing 5 with x and 5.
⇒ 
subtracting 25 on both side.
⇒ 
cross multiplying
∴ x= 7.
Answer:
Side FE < Side DE < Side DF
Step-by-step explanation:
The traditional approach here is to solve x - 5y = -5 for y and then read off the coefficient of x (which is the desired slope):
-5y = -5 - x, or
5y = 5 + x
Then y = (1/5)x + 1. The slope is (1/5).
