Answer: 100
Step-by-step explanation:

3 x 25 = 75
4 x 25 = 100
Divide the gross income by 12 to find his monthly pay:
29,700 / 12 =$2,475 per month.
Multiply his monthly pay by 7%:
2,475 x 0.07 = $173.25 into his 401(k) per month.
The answer is A.
D. None. Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees. Hope this helps.
