The first term of this series is:
The last term of this series is when
The sum of the first n terms of an arithmetic series when the first an last term is known is given by:
Where a=5 is the first term and l=27 is the last term.
Answer:
Step-by-step explanation:
we know that
When two lines are crossed by another line (transversal), the angles in matching corners are called Corresponding Angles.
When the line are parallel the corresponding angles are equal in measurement.
so
In this problem
-----> by corresponding angles
see the attached figure to better understand the problem
Solve for x
Subtract 50 both sides
Divide by 8 both sides
