Answer: 3
Step-by-step explanation:sdfdsfds
The answers are
1) ∠A = 53
°
2) ∠D = 127°
3) x = 5
4) AB = 7
<u>Step-by-step explanation</u>:
In parallelogram,
- Consecutive angles are supplementary (∠A + ∠B = 180°).
- Opposite angels are congruent (∠D = ∠B).
- Opposite sides are congruent (AB = DC).
1) find angle A :
Given, ∠B = 127°
∠A + ∠B = 180°
∠A = 180-127= 53
°
2) find angle D :
Given, ∠B = 127°
∠D = ∠B
∠D = 127°
3) find x :
AB = DC
(x+2) = (2x-3)
2+3 = 2x-x
x = 5
4) find AB
:
AB = (x+2)
AB = 5+2
AB = 7

Answer:
a / b = 1/7
b = a x 7
a / c = 4 /1
a = c x 4
b = a x 7
= c x 4 x 7
= c x 28
b is 28 times bigger than c
