Answer:
x= 60.1 degrees
Step-by-step explanation:
The triangle forms a right angle triangle
Opposite side of angle x = 13 ft
Hypotenuse of the triangle = 15
We know the opposite side and the hypotenuse
So we use trigonometric formula sin(x)
When we move 'sin' to the other side it becomes 'sin^-1'
x = 60.073565
(5, 9), (5, -2)
x1 y1 x2 y2
Plug in what we know:
Subtract:
We can't divide by zero, so:
Possible values of x is -4 or -16
<h3>How to solve?</h3>
+ 20x +100 = 36
+ 20x + 100-36 = 0
+ 20x + 64 = 0
Using middle term split
In this method splitting of middle term in to two factors, In Quadratic Factorization using Splitting of Middle Term which is x term is the sum of two factors and product equal to last term.
+ 4x + 16x + 64 = 0
x(x+4) + 16(x+4) = 0
taking common (x+4)
(x+4)(x+16) = 0
Either
x+4 = 0
⇒ x = -4
or (x+16) = 0
⇒ x = -16
Thus possible values of x is -4 or -16
