The sum of the measures of the interior angles of a convex polygon is 1080° Classify the polygon by the number of sides

lozanna [386]

Answer:

(n-2)×180=1080

180n -360=1080

180n = 1080+360

180n =1440

dividing by 180

n=8

hence it is a regular polygon with 8 sides .I.e it is an octagon

Step-by-step explanation:

we are given the total interior angles in the polygon and we know that the formula to find the total interior angles of a polygon is (n-2) ×180

where n is the number of sides

grandymaker [24]

Answer:

t ≥ 1.5

Step-by-step explanation:

Lets take time for practicing the piano to be t

The number of hours to practice per week should be at least 6 hours

This is written as t ≥ 6

She already practiced 3 hours this week, thus the remaining hours to practice should be

t ≥ 3

The minimum remaining hours to practice for the remaining 2 days should be

t=3

If these hours are evenly divided, then in a single day she should practice

for t ≥ 1.5

a/q. 3x + 2x = 300000

 5x = 300000

x = 300000/5

x= 60000

Leona = 60000*3 = 180000

Janet = 60000*2 = 120000
