I think its B. Solution has been up. just click the photo and see.
Given:
Bl parallel to RA.
To find:
The value of x.
Solution:
In triangle ATR and ITB,
[Common angles]
[Corresponding angle]
[AA property of similarity]
We know that the corresponding sides of a similar triangle are proportional. So,



On cross multiplication, we get




Therefore, the correct option is C.
Answer:
Subtract 63 from both sides
Step-by-step explanation:
we always have to try to clear the incognita that in this case is going to be h
First we
Subtract 63 from both sides
then
Divide by -7 on both sides
19 - 7h = 63
19 - 7h - 19 = 63 - 19
- 7h = 44
-7h/-7 = 44/-7
h = -44/7
Answer:
L(f(t)) = 
Step-by-step explanation:
f ( t ) = 10 cos ( 12t + 60°) u(t)
attached below is a detailed solution of the given problem
L(f(t)) =
