Question

Examine whether you can construct ∆DEF such that EF=7.2cm, angle E =110° and angle F=80° . Justify your answer.

Answer 1

Answer:

No we can't.....

Step-by-step explanation:

Since it is given that

angle E = 110

and angle F = 80

But we know that the sum of all the angles of a triangle is 180 degrees

but here we see that these 2 angles are making an angle sum > 180 degrees      

And thus this triangle is not possible.....
