The longest side of the triangle has to be less than the sum of the two other sides.
A ⇒ 7 + 8 = 15
B ⇒ 8 + 5 < 14
C ⇒ 6 + 3 < 10
D ⇒ 2 + 6 > 7
The answer is D, because the longest side length (7) is shorter than the two other side lengths (2 and 6).

have a good day :)
Step-by-step explanation:
Answer:
in 90 minutes he ran 30 laps
there is 60 minutes in a hour so the fraction would be
2/3 so we have to multiply this by 30
2/3*30=20
He can run 20 laps in a hour

**All 3 angles of a triangle have a sum of 180°.**
So if 2 of those 3 angles are 62.5°, you would just subtract that by 180°.
180 - 62.5 = 117.5
The third angle would have to be 117.5°.
