Answer:
→ 50°
→ Acute triangle
Step-by-step explanation:
the measure of the third angle = 180 - (60 + 70) = 180 - 130 = 50°
definitions=======================================
Acute angle : it’s an angle that measures less than 90°.
Acute triangle: it’s a triangle with three acute angles.
………………………………………………………………………………………………
The measures of the angles in our triangle are respectively 60° , 70° , 50°
