Answer:
8
Step-by-step explanation:
If we assume the '17' is the hypotenuse ( the Q does not say)
then 15^2 + x^2 = 17^2 via the pythag theorem for right triangles
x = 8
Answer:
is used to prove the given equation.
Step-by-step explanation:
We have given an equation:

We will consider right hand side first
tan x can be written as:

So, on substituting tan x in the left hand side of the given equation we get:

Cancel common term from denominator and numerator which is cosx we get

And we have an identity:


Hence, right hand side is equal to
.
Answer:
x = 4
Step-by-step explanation:
11x= 6x +20
-6x -6x
(subtract 6x from both sides)
5x = 20
/5x /5x
divide 5x from both sides
x=4
Answer:
Perimeter = 21.58 units
Step-by-step explanation:
Perimeter of a polygon = Sum of measures of all sides of the polygon
Perimeter of the quadrilateral LEAP = PL + AE + EL + LP
= 4.47 + 4.47 + 6.32 + 6.32
= 21.58 units
