Equations : 4x + y = 2 x - y = 3
Equation 1 4x + y = 2 x - y = 3
x y x y
-2 10 -2 -5
-1 6 -1 -4
0 2 0 -3
1 -2 1 -2
2 -6 2 -1
The point where both lines cross is (1, -2) so it is the solution.
since 92 is not divisible into 93 by a whole number ratio, 92/93 is already in lowest terms
AB² = AC²+BC²
AB² = 9²+12²
AB²= 225
AB= 15
SinA = 12/15
A = Sin-¹(0.8)
M`A = 53°
M`B = 90- A = 90-53= 37°
