Question

Which of the following measures of sides and angles form a triangle? *
(a) LA = 60º, LB = 60º and AC = 5.4 cm
(b) LP = 70º, LQ = 115º and PQ = 4.7 cm
(c) AB = 4 cm , BC = 4.8 cm and AC = 10 cm
(d) AB = 4 cm , BC = 5 cm and AC = 11 cm​

Answer 1

Answer:

answer is option A

Step-by-step explanation:

because sum of all angles of triangle is 180 degree

an two angles are given there is no matter that what is length of side

Answer 2

Answer:

A) LA =60° ,LB = 50° and AC = 5.4cm

Step-by-step explanation:

Option A can be a triangle .

While ,

Option B can't cause the sum of 2 angles of traingle that is LP and LQ is greater than 180°. In a triangle sum of 3 angles is equal to 180°.

option C and D , cannot be triangle because the sum of two sides is smaller than the third side .

(We know that sum of 2 sides of triangle is always greater than the third side. )

Hence only option A is correct
