Question

Kevin drew a triangle with angle measures of 30 degrees and 40 degrees and side measures of 5 cm, 7cm, and 8 cm. Explain, using sides and angles, which type of triangle Kevin drew. help 50 points

Answer 1

in this there is two angles are already given

and, we know that, sum of triangle is 180•

so, 30•+40•+x=180•

then, we get x=110•

so, this is obtuse angled triangle

and, sides are a+b>c

b+c>a

c+a>a

Answer 2

By angle sum property, which states that"

the sum of all three measures of a triangle is 180 degrees".

Let the third angle be 'x'

So, 30° + 40° +2= 180°

x = 110°

So, he draws a triangle with angle measures as 30 degree, 40 degree and 110 degree and and side measures of 5 cm, 7 cm, and 8 cm.
