The interior angle of a regular

Mathematics
1 answer:
Alexxx [7]3 years ago
7 0

Answer:

12

Step-by-step explanation:

The sum of the exterior and interior angles = 180°

let x be the measure of the exterior angle then interior angle is 5x and

5x + x = 180

6x = 180 ( divide both sides by 6 )

x = 30

The sum of the exterior angles of a polygon = 360°, thus

number of sides = \frac{360}{30} = 12

Find the substitution 2x+3y=-5 and y=-x+5
tatuchka [14]

Answer: x = 20, y = -15

Step-by-step explanation:

Since we already know that y=-x+5, we can just substitute in that value of y into the other equation:

2x+3y=-5\\2x+3(-x+5)=-5\\2x-3x+15=-5\\-x=-5-15\\-x=-20\\x=20

with the value of x, we can find the value of y:

y=-x+5=-20+5=-15

hello : 
let : x the length   and  y  the <span>width
</span>the area is : xy  and ; x/y = 3/2
xy =5454  ...(1)
x = (3/2)y  ... (2)
subsct in (1) : (3/2)y ×y = 5454
3y² = 10908
y² = 3636....continue    calculate : y
