Answer:
Step-by-step explanation:
Since AB and ED are parallel and AE is the transversal, angle A and E are congruent
So m∠E = m∠A = 50°
Answer:
B.4
Step-by-step explanation:
1.5(x+4) - 3 = 4.5( x-2)-----------------------open brackets on both sides
1.5 x +6 -3= 4.5x- 9.................................collect like terms
3+9 = 4.5 x- 1.5x
12=3x..................................divide by 3 both sides to get x
12/3=x
x=4

D. 3.0 x 10^8
#7
A. y = 3.5x + 7
#8
B. 5
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°
