Answer:
y = m x + b equation of a straight line
m m' = -1 condition for perpendicular lines
If y = 4 x - 7 then m = 4 so m' = -.25
Y = -.25 X + A we need to find A
A = Y + .25 * 8 = 2 + 2 = 4
Y = -.25 X + 4
Check:
2 = -.25 * 8 + 4 = -2 + 4 = 2
Answer:
43.5
Step-by-step explanation:
you just divide 435 by 10 and you get 43.5
Compare the values they have given you with the diagram. a, b and c are all sides of the triangle they want you to find the perimeter of. Knowing this, all you have to do is add a, b and c. h is not important because you don't count the altitude of a triangle when you calculate perimeter.
12 + 10 + 12 = 34
The perimeter of the triangle is 34 ft.
