Answer:
Is an equilateral triangle
Step-by-step explanation:
we know that
An equilateral triangle has three equal sides and three equal internal angles measures 60 degrees each
so
In this problem the triangle formed by the route has three equal sides (10 miles)
therefore
Is an equilateral triangle
Answer:
second one is the correct option which says 35+5x=90
Perimeter is the length of all the sides of a shape added together.
So to find the third side, we would subtract 9 and 18 from 49
49 - (9 + 18) = 22
The length of the third side is 22m.
(3^2)^-2
9
9^-2 = 1/9^2 ---> 1/81
should be 1/81
Answer:
2y -x + 6 = 0
Step-by-step explanation:
Here a equation and a point is given to us and we are interested in finding a equation which is perpendicular to the given equation and passes through the given point .
The given equation is ,
Firstly convert this into slope intercept form , to find out the slope of the line.
Now on comparing it to slope intercept form which is y = mx + c , we have ,
And as we know that the product of slopes of two perpendicular lines is -1 . So the slope of the perpendicular line will be negative reciprocal of the slope of the given line. Therefore ,
Now we may use the point slope form of the line to find out the equation of the line using the given point . The point slope form is,
Now on substituting the respective values we have,
