perimeter of a triangle ABC
Perimeter of a Triangle
= AB + BC + CA
= 10cm + 8cm + 12cm,
(add the length of each side of the triangle).
= 30cm
Perimeter of the triangle = Sum of the sides.
Answer:
x = - 2
Step-by-step explanation:
y = 4 is the equation of a horizontal line parallel to the x- axis.
Thus a perpendicular line will be vertical and parallel to the y- axis.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 2, 1) with x- coordinate - 2, thus
x = - 2 ← equation of perpendicular line
Draw triangles within the ramps and since they are right triangles, use the pythagorean theorem based on what was given and solve
