The answer is A well that’s what I got
The answer is A, The intersection point is (-5,3) and the equation of the graphs are y = x + 8 and x + y = -2
Périmètre rectangle = 2 ( longueur + largeur)
périmètre carré = 4 x côté
I am not quite sure what the question asks for,
But this is what i assume it wants:
Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A
: It looks like this in the calculator
× cos A=
(0.6489)
(
and cos cancels out)
A=
(0.6489)
A=49.54°
check:
cos 49.54=0.6489 (its right!)
