Step-by-step explanation:
X-23=18
Because difference means subtract
1. AB*BE=CB*BD
Reason:Given
2.
Reason:
This result comes from the statement 1 because by moving BE to the righ hand side and BD to the left hand side, we have the previous result. This property is also know as proportion of the corresponding sides.
3.
Reason: They are vertical opposite angles.
4.
Reason. SAS (side-angle-side) theorem.
This theorem states that if two side and the included angle are equal to the two sides and the included angle of another triangle, then the triangles are congruent.
where the congruent sides are colored in the same color. The blue angle measure the same in both triangles and it is the included angle between sides red and green.
Answer: Time = 1.5hours or 1 hour 30minutes
Step-by-step explanation:
Given;
Carrie can inspect a case of watch in 5 hours
if n represent the task,
Carrie's rate C = n/5
James' rate J = n/3
Their combined rate is=n/5 + n/3 = 8n/15
Carrie After working one hour, he would have completed n/5 of the task.
Therefore, the remaining fraction of task is 4n/5
To complete the remaining fraction of task by the two of them, the time taken can be given as;
Work done = rate × time
Time = workdone/rate
Workdone = amount of task remaining = 4n/5
rate combined= 8n/15
Time = (4n/5)/(8n/15)
Time = 1.5hours or 1 hour 30minutes
The value of D is 5 since it has the longest length
