Answer:
x = 36°
Step-by-step explanation:
interior angle of regular pentagon: 180 x (5-2) /5 = 540 / 5 = 108
∠C = 108
CD = CB ∠CDB = ∠CBD = (180 - ∠C) /2
x = (180 - 108) / 2 = 36°
Answer:
go a head what can i help you with
8:7...added = 15
(8/15(90) / 2= 48/2 = 24
(7/15(90) / 2 = 42/2 = 21
dimensions are : 24 ft by 21 ft
Answer:
905
Step-by-step explanation:
arithmetic sequence are in form
a(n)=a(0)+d(n-1)
a(0)=25
common difference: d=35-25=10
a(n)=25+10(n-1)
a(89)=25+10(88)=905
If you were to put 7 as the width than add 6 to get your length (13).Then add 13+13 and 7+7 26+14=40 So basically length is 13 and width is 7
