sin²(x) - 0.25 = 0
sin²(x) + 0.5sin(x) - 0.5sin(x) - 0.25 = 0
sin(x)[sin(x)] + sin(x)[0.5] - 0.5[sin(x)] - 0.5[0.5] = 0
sin(x)[sin(x) + 0.5] - 0.5[sin(x) + 0.5] = 0
[sin(x) - 0.5][sin(x) + 0.5] = 0
sin(x) - 0.5 = 0 or sin(x) + 0.5 = 0
sin(x) = 0.5 sin(x) = -0.5
sin⁻¹[sin(x)] = sin⁻¹(0.5) sin⁻¹[sin(x)] = sin⁻¹(-0.5)
x = 30°, ¹/₆π radians x = 210°, 1¹/₆π radians
150°, ⁵/₆π radians 330°, 1⁵/₆π radians
the answer is 58
because to find the perimeter all you do is add all the sides together which is 12+15+8+9+14=58
i hope this helps you
35/7 = 5$ per car so 4x5= 20$
Answer:
The area is 35 inches
Step-by-step explanation:
You will need to cut the shape into 3 parts
the 3 by 3
2 by 5
and 4 by 4
after that you multiply the numbers to get the area of the 3 parts.
The final step is to add them all up
