14.16 is the answer to your problem
Answer:
11%
Step-by-step explanation:
We have been given that
Principle = Rs 2350
Time = 2 years
Total amount = Rs 2867
Therefore, Interest earned is given by
I = Total amount - Principle
I = 2867 - 2350
I = Rs 517
Formula for simple interest is

Therefore, annual rate of interest is 11%
Answer:
Step-by-step explanation:
The answer to this is 65.
Remember that the angles opposite of each other equal to 180. So a+c=180 and b+d=180.
First, we solve for x. Since we know that b and d equal to 180, we subtract 148 from 180.
180-148=32. x=32.
Then we plug that in the expression for angle a.
2x+1 becomes 2(32)+1
2*32=64
64+1=65.
a=65
