Find the value of the variable.
1 answer:
Answer:
x=6 and y=3√3
Step-by-step explanation:
let the sides be A, B and C ( As shown as in the figure attached below)
tan 60° = opposite/adjacent
tan60° = BC/AB
√3 = y/3 ( as value of tan60=√3 and as BC=y)
Therefore,
y = 3√3
According to pythagoras therom,
AC^2 = AB^2 + BC^2
x^2 = 3^2 + y^2
x^2 = 9 + 3√3^2
x^2 = 9 + 27
x^2 = 36
Therefore,
x=6
Hope the answer helps :)

Answer:
Step-by-step explanation:
The equation of the line WX is, 2x + y = - 5
⇒ y = - 2x - 5 .......... (1)
This equation is in slope-intercept form and the slope is - 2 and the y-intercept is - 5.
Now, if a line perpendicular to equation (1) having slope m then, m × (- 2) = - 1
⇒
{Since the product of slopes of two mutually perpendicular straight line is - 1}
Therefore, the equation of the perpendicular line is
, where c is a constant and we have to find it.
This above line passes through the point (-1,-2) and hence
⇒
Therefore, the equation of the line will be (Answer)
