D=62*
triangles=180*
use the equation 90+28+d=180
<span>1). 16 x 3/4
Step One- 16/1 x 3/4
Step two- 4 goes into 16 four times so cancel the 4 and change the 16 to a 4...
Step three- 4 x 3=12
2). (81/16) divided by (9/14)
Step one- Since its division we use (FREEZE CLAP FLIP)= Freeze (81/16) Clap the division sign and change it to a multiply sign and Flip the riprocals (9/14)
The equation is now 81/16 X 14/9
Next 81 is divisible by 9 and 16 and 14 are divisible by 2
So the new formula i s 9/8 X 7/1
Solution=63/8
3). 2/3 divided by 4/3
Flip the reciprocals for the 4/3
New equation is 2/3 X 3/4
2 and 4 are divisible by 2 and the 3's cancel each other out
Solution: 1/2</span>
Answer:
The answer is 15x + 7
Step-by-step explanation:
Since the perimeter of a REGULAR polygon is the number of sides multiplied by the length, and the lengths of the sides are all different, it can be assumed that this is an irregular polygon. That means the formula to find the perimeter changes to all the sides added together.
1 x + 3
2 x - 4
5 x + 0
<u>+ 7 x + 8</u>
15 x + 7
Station A is at a distance of 28.83 miles from the storm
<h3>
Sine rule</h3>
Sine rule is used to show the relationship between the sides of a triangle as well as their opposite angles. It is given by:
From the diagram:
Also:
Hence:
- C + A + B = 180°
- C + 29 + 124 = 180
- C = 27°
b = distance station A from the storm, c = AB = 27 miles
Using sine rule:
Station A is at a distance of 28.83 miles from the storm
