The measures of two angles of a triangle are 25° and 87°. Is the triangle acute, right, or obtuse? A. Acute; the measure of the third angle is 68°. So all three angles are acute.
B. Acute; the measure of the third angle is 78°. So all three angles are acute.
C. Obtuse; 25° + 87° = 112° and 112° is an obtuse angle.
D. Right; 25° + 87° = 112° and 202° – 112° = 90°.

Apolygon is shown on the graph: a polygon is shown on the coordinate plane. vertices are located at 3 comma 5, 1 comma 3, 1 comma 1, 2 comma 0, 4 comma 0, 5 comma 1, and 5 comma 3. what effect will a translation 3 units down and 2 units left have on the polygon? be sure to address how it could impact the angles, side lengths, and congruency between the original pre-image and the image. xd i need
