The triangle is obtuse because 11 cm > 100
Basically
Other side + other side > longest side
In this case…
6 + 5 = 11 is greater than the longest side which is 10, so it would be obtuse
Hope this helps!!
Answer:
The AP is 1, 11/2, 10, 29/2, 19, ....
Step-by-step explanation:
Let the first term be a and d be the common difference of the arithmetic progression.
ATQ, a+2d+a+6d=38, 2a+8d=38 and a+8d=37. Solving this, we will get a=1 and d=9/2. The AP is 1, 11/2, 10, 29/2, 19, ....
2 would be the correct answer.
10/5 = 2/1 = 2
