Given:
In the given triangle,
With respect to 30°, the perpendicular = 9, the base = x and the hypotenuse = y
To find the value of x and y.
Formula
By Trigonometric ratio we get,
and
Now,
Putting, perpendicular = 9 and we get,
or,
or, [ by cross multiplication]
Again,
or,
or, [ by cross multiplication]
Hence,
The value of x and y is 9√3 unit and 18 unit respectively.
Answer:
The gradient of lines A is 8 and B is -4
Step-by-step explanation:
As we know, the gradient of a line is its slope.
The formula to find the slope of a linear line is:
m =
As we can see the line A goes through points:
C (x1, y1) = (0, -6)
D (x2, y2)= (2.5, 14)
<=> the slope of line A is:
=
=
=
As we can see the line A goes through points:
E (x1, y1) = (2, 0)
F (x2, y2)= (0, 8)
<=> the slope of line B is:
=
= -4
Hence, the gradient of lines A is 8 and B is -4
The answer is c because the variable behind the number s are equal
