Answer:
sorry but i need the points <3
Step-by-step explanation:
If a parallelogram has an area of 7 square units, and the height corresponding to a base is
units, then the base is 28 units.
As per the question statement, a parallelogram has an area of 7 square units, and the height corresponding to a base is
units.
We are required to find out the base of the parallelogram.
To solve this question, we need to know the formula to calculate the area of a parallelogram, which goes as
Area of Parallelogram = (Base * Height)
Putting our data obtain from the question statement, in the above-mentioned formula, we can calculate the value of the base of our concerned parallelogram, i.e.,

Therefore, base of our concerned parallelogram is 28 units.
- Parallelogram: In Euclidean geometry, a parallelogram is a four-sided, plane, closed figure (Quadrilateral) with two pairs of parallel, opposite sides.

I assume you're asked to solve
4 cos²(<em>x</em>) - 7 cos(<em>x</em>) + 3 = 0
Factor the left side:
(4 cos(<em>x</em>) - 3) (cos(<em>x</em>) - 1) = 0
Then either
4 cos(<em>x</em>) - 3 = 0 <u>or</u> cos(<em>x</em>) - 1 = 0
cos(<em>x</em>) = 3/4 <u>or</u> cos(<em>x</em>) = 1
From the first case, we get
<em>x</em> = cos⁻¹(3/4) + 2<em>nπ</em> <u>or</u> <em>x</em> = -cos⁻¹(3/4) + 2<em>nπ</em>
and from the second,
<em>x</em> = <em>nπ</em>
where <em>n</em> is any integer.
Answer:
<h2>1.326 ......</h2>
Step-by-step explanation:
³√81 = 4.326
³√216 = 6
⁴√16 = 2
√225 = 15
<h3> X = ³√81 - 8 ³√216 + 15 ⁴√16 + √225 </h3>
X = 4.326 - (8×6) + (15×2) + 15
X = 4.326 - 48 + 30 + 15
X = 49.326 - 48
X = 1.326 ............
