Can someone help me please ( get brainliest)

5:30

My Logic:

First you need to add all of the hours of work he did together (3 3/4).

now i would convert that to hours and minuets (3 hours and 45 min).

now we know he ended at 9:15 so you must subtract the time spent.

1: 1 triangle

2: 1 triangle

Step-by-step explanation:

The first one is an equilateral triangle. There is no other triangle possible to make other than that one.

The second one is a 30-60-90 triangle. I would assume you know something about them. Since we know that, we can automatically tell the measures of the other sides. The picture is the only triangle you can form with those specifications.
