To solve this problem, we just have to use trigonometric ratios and apply which of the ratios is needed here and proceed to solve. The value of side AC is 2.85 units
<h3>Trigonometric Ratio</h3>
In the given diagram, we have the value of angle and hypothenuse and we are required to find the adjacent side of the triangle.
Data;
- Angle = 32.9 degrees
- Hypothenuse = 3.4
Let's use cosine rule for this.
Proceed to substitute the values into the equation and solve.
From the calculations above, the value of side AC is 2.85 units

Answer:
You just need to measure it's two diagonal lines, then times them together and divide 2.
The area of the square is s×s
= 4×4 = 16 m²
The area of a quarter circle is (πr²)/4
= 3.14 × 16/4
= 3.14 ×4
= 12.56 m²
Therefore, the total area is;
= 16 +12.56
= 28.56 m²
≈ 28.6 m²
Place the middle part of the protractor (where the lines intersect) on the vertex of the angle, then just look at the number the other arrow’s pointing!
Answer: x = ± i , x = ±√2i are solution .
Step-by-step explanation:
Given : 
, use u substitution to solve.
To find : what are the solutions of the equation .
Solution : We have given that .
Let consider 
= u .
Substitute u = in given equation .
.
On factoring
.
Taking common
u( u+2) +1 (u+2) = 0.
On grouping
(u+1) (u+2) =0
Now, u+1 = 0 ⇒ u = -1.
u+2 = 0 ⇒ u = -2.
In term of x, plugging = u.
= -1 ; = -2.
taking square root both side
x = ± i
x = ±√2i.
Therefore, x = ± i , x = ±√2i are solution .
