Answer:82 notes
Step-by-step explanation:
18.57*890=16527.30
16527/200=82.6365
Nearest whole number=82
Answer:
x + 150 deg = 180deg (being co-interior angles)
:. x = 30 deg
2. y^2 + 7= 32 ( opposite sides of parallelogram are equal)
or, y^2 = 25
or y^2 = 5^2
: . y = 5
3. k= 2y^2 ( opposite sides of parallelogram are equal)
or, k = 2× 5^2
: . k = 50
Step-by-step explanation:
Pythagoras : the lengths are the hypotenuses of the right-angled triangles created by the differences of the x and the y coordinates.
so,
AB² = (0 - -3)² + (2 - 8)² = 3² + (-6)² = 9 + 36 = 45
AB = sqrt(45) ≈ 6.7
CD² = (-2 - 0)² + (2 - -4)² = (-2)² + 6² = 4 + 36 = 40
CD = sqrt(40) ≈ 6.3
I think it’s A but if it’s not then try c
