A right triangle is formed by connecting coordinates (5,-2), (2,-3), and (-1,6). What is the area of the triangle in square units?wer:
Step-by-step explanation:
Answer:
36.9 degrees
Step-by-step explanation:
Calcolate the sine of the angle BAC by dividing the opposite cathetus by the hypthenuse. That gives us 3/5 = 0.6. Now use the calculator to calculate the amplitude of the amgle by using the sin^-1 (or arcsin) function, so write sin^-1(0.6)=36.9.
The ratio to compare would be C) 5 to 3 because there are 5 red amrbels and 3 blue ones
