Answer:
Distance = 10 km
Step-by-step explanation:
Let x be the number of hours taken from school to town and y be the number of hours taken back to the school
Then distance covered during first trip would be 10x (distance = speed*time) and during the second trip would be 8y. Both distances are equal.
=> 10x = 8y
Dividing both sides by 2
=> 5x = 4y
=> 5x-4y = 0 ------------------(1)
<u><em>The total time for both the trips is:</em></u>
=> x + y = 2.25 -------------------(2)
Multiplying eq (2) by 5
=> 5x+5y = 11.25 ---------------(3)
Subtacting (3) from (1)
=> 5x-4y-5x-5y = 0-11.25
=> -4y-5y = -11.25
=> -9y = -11.25
Dividing both sides by -9
=> y = 1.25 hrs
Putting in (2)
=> x + 1.25 = 2.25
=> x = 2.25 - 1.25
=> x = 1 hr
<u><em>Now, Calculating the Distance</em></u>
=> Distance = 10x
=> 10 ( 1 )
=> Distance = 10 km
Answer:
Step-by-step explanation:
<u>ΔABD ≅ ΔAEC because:</u>
- AD = AC = 17
- ∠A is common and congruent to itself
We have two sides and the included angle congruent - SAS
<u>Corresponding parts of congruent figures are congruent:</u>
Now, <u>∠CED is exterior angle and exterior angle is same as sum of non-adjacent interior angles:</u>
- m∠CED = m∠A + m∠C
- 79° = 42° + p°
- p = 79° - 42°
- p = 37°
70 because 55+55 = 110 and a triangle is 180 so 180-110= 70 and X is opposite to the angle we worked out as the missing one
