Answer:
50°
Step-by-step explanation:
Opposite angels of a parallelogram are congruent to each other.
This means:
<ADC = <ABC
<ADC = 38° + 12°
<ADC = 50°
Since <ADC = <ABC, therefore,
<ABC = 50°

Answer:
The value of y is 3 cm.
Step-by-step explanation:
Given,
Perimeter of triangle = 
Solution,
Lets redraw the triangle with nomenclature ABC, given in the attachment.
∴P(ΔABC) = 29 cm (P stands for perimeter)
Length of AB = 
Length of BC = 
Length of CA = 
Now, we all know that the perimeter of a triangle is sum of all the three sides of triangle.
P(ΔABC) = Length of AB+Length of BC+Length of CA
On substituting the values, we get;
Length of AB =
Length of BC =
Length of CA =
Hence the value of y is 3 cm.
The train will pass the jogger in 36 seconds.
Length of train = 120m
Speed of train = 45kmph
Distance by which the jogger is ahead of the engine of the train = 240 m
Speed of jogger = 9 kmph
To pass the jogger, the train will have to cover the length of the train and the distance by which the jogger is ahead of the engine of train.
Hence,
Distance = 120 + 240 = 360m
As,
Time = Distance/Speed
Relative speed of train w.r.t jogger = 45 - 9 = 36 kmph = 10 m/s
Hence,
Time = 360/10 = 36 seconds.
