Step-by-step explanation:
Imagine 8 pieces of fruit and 2 bars are arranged in a line such that the 2 bars split the rest of the fruits into 3 portions.
Hence the number of ways = 10C2 = 45.
Answer:
4/25 maybe?
Step-by-step explanation:
The answer to the above question can be explained as under -
We know that, the sum of angles of triangle is 180°.
So, vertex angle plus base angles are equal are equal to 180°.
Let the vertex angle be represented by "v" and base angles be represented by "b".
Thus, v + b + b = 180°
So, v + 2b = 180°
Next, the question says, the vertex angle is 20° less than the sum of base angles.
Thus, 2b - 20° = v
<u>Thus, we can conclude that the correct option is A) v + 2b = 180°, 2b - 20° = v</u>
