The correct answer is 1/3
Answer:
y=50 x=80
Step-by-step explanation:
z(3rd spot)=y=50
x=180-2*50=80
Decagon = 10 sides or 10 anglesTotal angle is equal to 360°
360° ÷ 10 = 36°
I haven't seen the image of A, that is why, I started with angle A as 36°
∠A = 36°∠B = 36° + 36° = 72°∠C = 72° + 36° = 108∠D = 108° + 36° = 144°∠E = 144° + 36° = 180°∠F = 180° + 36° = 216°∠G = 216° + 36° = 252°∠H = 252° + 36° = 288°∠I = 288° + 36° = 324°∠J = 324° + 36° = 360°
Answer:
8 m, 17 m and 22 m
Step-by-step explanation:
The first side is x
The second is 1 more than twice the first = 2x + 1
The third is 2 less than 3 times the first = 3x - 2
Sum the 3 sides and equate to 47
x + 2x + 1 + 3x - 2 = 47, that is
6x - 1 = 47 ( add 1 to both sides )
6x = 48 ( divide both sides by 6 )
x = 8
Thus
side 1 = 8 m
side 2 = 2x + 1 = 2(8) + 1 = 16 + 1 = 17 m
side 3 = 3x - 2 = 3(8) - 2 = 24 - 2 = 22 m
I think A=12bh I hope it’s right
