Answer:
D & E are correct options
1- es 96
A= (-3)(3-9-11) =(-3) x (-17) =51
B= (-1-11+7)(-3+12) = -5x9 = -45
A--B= 51--45 = 96
2- es 2929
p=-3(5-(3-7-1)) =-3(5-)-5))= -3(5+5) =3x10 =30
Q= -(-5(-5(-5+1))) = -(-5(-5(-4))) = -(-5x20) = -(-100) = 100
(p-1)(Q+1) = (30-1)(100+1) = 29x101= 2929
Answer:
The measurement of the required angle = 116°
Step-by-step explanation:
Let the measure of its supplement = x
The measurement of the required angle = 2x - 12
x + 2x -12 = 180
3x - 12 = 180
3x = 180 + 12
3x = 192
x = 192/3
x = 64°
The measurement of the required angle = 2 * 64 - 12 = 128 - 12 = 116°
The answer for your question 186.
