It is 36*4= 144 That is the answer for both corecction 214
Point A=-1.3
Point B= 1.3
These 2 points are reciprocals, which means that their sum is Zero. So basically they are exact opposites.
Use the Pythagorean Theorem.
a² + b² = c²
3² + b² = 19²
9 + b² = 361
b² = 352
b = 4√11
Now, solve for the remaining angles by using the trigonometric ratios:
Sine = opposite/hypotenuse
sin(A)= 3/19
sininverse(3/19) = 9.1 = angle A
180-9.1-90 = 80.9 = angle B
