Q200
A triangle with the lengths of its sides proportional to the numbers 7, 24 and 30 is:
A.
acute angled
B.
obtuse angled
AnswerC.
not possible
D.
right angled
Answer: Option B
Solution
Answer: Option B
Solution:
Let, Perpendicular = 7 cm
Base = 24 cm
Hypotenuse = 30 cm
Here, P2 + B2 < C2
(7)2 + (24)2 < (30)2
49 + 576 < 900
625 < 900
Therefore triangle is obtuse angled triangle.
