Answer :
<u>A the triangle is not a right </u><u>triangle</u>
<u>D </u><u>costheta</u><u> </u><u><0</u>
The law of cosines says:
a²=b²+c²−2bccos(θ)
Rewriting:
2bccos(θ)=b²+c²−a²<0
So cos(θ)<0cos(θ)<0 since 2bc>02bc>0. Since 0<θ<π0<θ<π in any triangle,
π/2<θ<π
So:
1. θ is not an acute angle.
2 The triangle is not a right triangle. In a right triangle, one of the angles is 90 degrees and the other two are then less than 90 degrees. This triangle has an angle greater than 90 degrees.
3. cos(θ)<0 is true.
4. cos(θ)>0 is false -3 says cos(θ) is negative; a number can't be both positive and negative.
