Answer:
x = 3 , X = -3
In x 2 = 9 , you need to get rid of the power of 2 in order to isolate just x This involves finding the square root. √ x 2 = x However there are 2 possible answers to a square root, a positive or a negative answer. x = ± √ 9 x = ± 3
Answer:
97°
Step-by-step explanation:
The sides that are equal are 4.6
One of the sides length is 4.6, and its opposite angle is 97. If there is another line that has a length of 4.6 in the same figure, it's angles should also be 97 degrees.

Step-by-step explanation:
Formula for area of a triangle :
<u><em>Area (triangle) = 1/2 × base × height</em></u>
<u><em /></u>
=============================================================
Solving :
<u>Triangle 1 (Top Left)</u>
⇒ Area = 1/2 × 11 × 3
⇒ Area = 33/2
⇒ Area = 16.5 in²
<u>Triangle 2 (Top Right)</u>
⇒ Area = 1/2 × 8 × 7.2
⇒ Area = 4 × 7.2
⇒ Area = 28.8 cm²
<u>Triangle 3 (Bottom Left)</u>
⇒ Area = 1/2 × (5.5 + 5) × 10.4
⇒ Area = 10.5 × 10.4
⇒ Area = 109.2 m²
<u>Triangle 4 (Bottom Right)</u>
⇒ Area = 1/2 × (2 + 7) × 5.5
⇒ Area = 9 × 2.75
⇒ Area = 24.75 in²
By definition, the arc length is given by:
S = R * theta
Where,
Theta: central angle
R: radio
Substituting the values we have:
S = (1600) * (π / 8)
Rewriting we have:
S = 200π feet
S = 628.3185307 feet
Round to the nearest foot:
S = 628 feet
Answer:
The length of the curve to the nearest foot is 628 feet.
Do you have a picture if not you just mutilply and get 12 I think
