4 0

Answer:

50.24

Step-by-step explanation:

1/4x3.14xr^2

r=16 because of the length

90/360= 1/4

so

1/4x3.14x16^2/4

=50.24

4 is our denominator because of the denominator on the fraction

Find one of the solutions to the following absolute value equation:<br> 26 + 4) = 48
Sindrei [870]
Answer : MAYBE 18 (?)
I’m not 100% sure
Explanation: you always solve what’s is parentheses “( )” first so then you get the equation
30 = 48
Then ( this is the part I’m not sure about)
You subtract 30 out that means 30-30=0 & 48-30 = 18 so that’s where I found my answer but idk I haven’t done absolute value since Algebra 1 !!

Imagine you are responsible for writing an advice column about mathematics. The following question is submitted to your column:
marissa [1.9K]

Explanation:

There are two different formulas that are useful with the given information:

  Area = (1/2)ab·sin(C)

  Area = √(s(s-a)(s-b)(s-c)) . . . where s=(a+b+c)/2

It does not matter which sides are designated a, b, and c. Angle C will be opposite side c.

The third angle can be computed based on the fact that the sum of angles in a triangle is 180°. It will be 180° -32° -28° = 120°. The least-to-greatest order of the angles is the same as the least-to-greatest order of the length of the opposite side. So, we might have ...

  • a = 7, A = 28°
  • b = 8, B = 32°
  • c = 13, C = 120°

Utilizing the first formula, the area is ...

  Area = (1/2)(7)(8)sin(120°) = 14√3 ≈ 24.249 . . . square units

Utilizing the second formula, the area is ...

  s = (7+8+13)/2 = 14

  Area = √(14(14-7)(14-8)(14-13)) = 14√3 ≈ 24.249 . . . square units

__

For the answer to be complete, it should be noted that using either of the other two angles will give different results for the area. That is because those angles are not exact values, but are rounded to the nearest degree. Using the first formula with the different angles, we get ...

  • area = (1/2)(8)(13)sin(28°) ≈ 24.413 . . . square units
  • area = (1/2)(7)(13)sin(32°) ≈ 24.111 . . . square units

The first of these answers is a little high because 28° is a little more than the actual value of the angle. Likewise, the second of these answers is a little low because 32° is slightly smaller than the actual angle.

In short, the most accurate information available should be used if the answer is to be the most accurate possible. If the angles are exact, then their values should be used. If the side measures are exact, then their values should be used. In general, it will be easier to make accurate measurements of the side lengths than to make accurate angle measurements.
