Answer:
A is 360
Step-by-step explanation:
Answer:
V≈278.85
Step-by-step explanation:
AB=s(s﹣a)(s﹣b)(s﹣c)
V=ABh
s=a+b+c
2
Solving forV
V=1
4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=1
4·8·﹣64+2·(6·12)2+2·(6·12)2﹣124+2·(12·12)2﹣124≈278.8548
∠B = 52°
Since the triangles are similar then
∠C = ∠S = 56°
∠B = 180° - (72 + 56)° = 52°
Answer:
i think it is b. 3
Step-by-step explanation:
but don''t quote me on it
F(x) = -2(x - 3)² + 2
f(x) = -2(x - 3)(x - 3) + 2
f(x) = -2[x(x - 3) - 3(x - 3)] + 2
f(x) = -2[x(x) - x(3) - 3(x) - 3(-3)] + 2
f(x) = -2(x² - 3x - 3x + 9) + 2
f(x) = -2(x² - 6x + 9) + 2
f(x) = -2(x²) - 2(-6x) - 2(9) + 2
f(x) = -2x² + 12x - 18 + 2
f(x) = -2x² + 12x - 16
