Two sides have the same length
The third angle measures 70°
It is an acute triangle.
i know that because eat triangle is 180°, so
if we subtract 40° and 70° from 180°, we get
70°, meaning the three angles in the
triangle are 40°, 70°, and 70°. Because all of
the angles are under 90°, we know that it is
an acute triangle.
