Answer:
You are absolutely correct.
Step-by-step explanation:Equilateral, meaning all sides are the same size, and acute, meaning all angles are lower than 90 degrees. You are correct.
P'(-3,-8) Q'(-6,4) R'(1,-1)
This should be correct! Hope I helped!
Rule of trigonometric functions:-
sin a = cos(90 - a)
Here a = 90°.
sin 90 = cos (90 - 90)
1 = cos 0.
cos 0 = 1.
So the cos 0 = 1.
