Answer:
a) 7 + (-4) = 3
b) (-6) + (-3) = -9
c) 2 -(-6) = 8
d) (-8) - (-13) = 5
Step-by-step explanation:
a) 7 + (-4)
= 7 + (-4)
= 3
b) (-6) + (-3)
= -6 - 3
= -9
c) 2 - (-6)
= 2 + 6
= 8
d) (-8) - (-13)
= -8 + 13
= 5

Answer:
a) Acute
Step-by-step explanation:
To clasify the triangle as Acute, Right, or Obtuse, we use the converse of the pythagorean theorem and see if c^2 is greater, less than, or equal to b^2+a^2.
So 16^2 ? 11^2 + 12^2
Since 11^2 +12^2 = 265 and 16^2 is 256, c^2 is less than b^2+a^2. So the triangle is acute.
