Answer:
D) .
Step-by-step explanation:
Given : If the first term of the series is 30 and the 14th term is 95,
To find : what is the sum of all the terms of the series.
Solution : We have given
First term = 30 .
14 th term = 95.
Sum of all term = .
Here, n = 14.
.
.
.
.
Therefore, D) .
Answer:
The value of x for the given transversal line t and parallel lines w , v is 17
Step-by-step explanation:
Given as :
The two parallel lines are w and v
The tow parallel lines are transversal intersecting by another line t at two points as show
Let The angle made by transversal when intersecting the line w is ∠a
And The angle made by transversal when intersecting the line v is ∠b
∵ line w ║ line v
∴ ∠a = ∠b ( corresponding lines axiom )
<u>So, from figure</u>
(4 x - 3)° = 65°
Or, 4 x = 65° + 3°
Or, 4 x = 68°
∴ x =
I.e x = 17
So, The value of x = 17
Hence The value of x for the given transversal line t and parallel lines w , v is 17 . Answer
