Answer:
108
Step-by-step explanation:
- Base+Base÷2 × height
- 10+7+7=10+14
- 24÷2=12
- 12×9=108
X equals 6 plus/minus i(square root) 42
Gradient= (y2-y1)÷(x2-x1)
= (-2-7)÷(2+1)
= -3
Subt the gradient into one coordinate point (2,-2)
Let 2 be x, -2 be y
Equation of line = y=mx+c
-2= -3(2) + C
therfore C is 4.
Equation of line is y=-3x+4
Answer:
∠P
Step-by-step explanation:
∠P is between NP and PE
You are basically finding the hypotenuse of a triangle with side lengths of 120 yards and 120 yards.
Using the equation a^2 + b^2 = c^2, solve for c (hypotenuse) where a and b are the side lengths (120 yards).
a^2 + b^2 = c^2
square root(a^2 + b^2) = c
square root (120^2 + 120^2) = c
square root (120^2 + 120^2) = c
square root (14400 + 14400) =c
square root (28800) = 169.7, rounded up to 170 yards of fencing needed.
