Answer:
obtuse because 6^2+10^2<10^2
Step-by-step explanation:
3x+8x=3333
11x=3333
X= 303
Boys 3x,so 3*303=909

Answer:
(c) Pi/4
Step-by-step explanation:
3pi/4 = (3 x 180) / 4 = 135 degrees
135 degrees is equivalent to (180 degrees - 135 degrees) 45 degrees
45 degrees = Pi/4
Therefore, the reference angle of 3pi/4 is Pi/4
Thus, the correct option is (c) Pi/4
