Find the size of each exterior angle of a regular octagon
51o
45o
40o
36o
Correct answer is B
Each Exterior ∠ = 360/n
= 360/8
= 45o
What is the value of k if the mid-point of the line joining (1 - k, - 4) and (2, k + 1) is (-k , k)?
-3
-1
-4
-2
Correct answer is A
(1-k+2) / 2 = - k and -4 + k + 1 = k
3-k = -2k and -3 + k = 2k
K = -3 and k = -3

\(\frac{40\sqrt{3}}{3}m\)
20 m
40√3 m
40 m
Correct answer is A

If the lines 2y - kx + 2 = 0 and y + x - k/2 = 0 Intersect at (1, -2), find the value of k
-4
-3
-2
-1
Correct answer is C
If the point of intersection is (1, -2), it implies that x = 1 and y = -2 when the two equation are solved simultaneously.
∴ substitute x = 1 and y = -2 in any of the equations
2y - k x + 2 = 0
2(-2) - k(1) + 2 = 0
-4 - k + 2 = 0
-4 + 2 = k
-2 = k
