Answer:
56 deg
Step-by-step explanation:
All internal angles of a triangle add up to 180 degrees
hence,
∠O + ∠R + ∠F = 180
x + (x+43) + (x-31) = 180
x + x+43 + x -31 = 180
3x+ 12 = 180
3x = 180 - 12 = 168
x = 168/3 = 56 deg
Answer:
(2, 4)
Step-by-step explanation:
The only point that satisfies the inequality is (2, 4).
(0, 5) : -0^2 +5 = 5 . . . . . not > 5
(1, 3) : -1^2 +5 = 4 . . . . . . 3 is not > 4
(2, 4) : -2^2 +5 = 1 . . . . . . 4 is greater than 1, so this point is in the solution set.
It’s the first one
x = -12 or x=2
