</span><span>21.05 - 7.25 = 13.80
</span>
CHECK OUR WORK:-

13.80 + 7.25 = 21.05
21.05 + 8.95 = 30
We were RIGHT!!!

Now lets divide:-

13.80 ÷ 2 = 6.90

In every triangle,if one of those three angles has his measure more than 90°,then the triangle is optuse.
If all three angles are 60°,it means the triangle equiangular.

If one of those three angles is equal to 90°,the triangle is right.

If all the angles of the triangle have their measure less than 90°,the triangle is acute.

_____________________________________________________________

Your triangle has an angle bigger than 90°,it means the triangle is optuse.

= 6(4)+ 5(-2)- 4(4)- 3(-2)+ 3(4)- 6(-2)

=24+(-10)-16-(-6)+12-(-12)

=24-10-16+6+12+12
