Answer:
Rs. 144
Step-by-step explanation:
To what the cost of each pen, divide 90/5
You get 18. So each pen costs 18.
Now multiply 18 by 8 and you would get 144.
So, it would cost Rs. 144
<A = 62 and <ABE = 18
Sum of interior angles in a triangle = 180
So
<E + <A + <ABE = 180
<E + 62 + 18 = 180
<E + 80 = 180
<E = 100
Answer: first option
100

Substitute the value of x = 2 to the equation:
