Question

Two angles of a triangle measure 45°and 55° respectively, find the measure of the third angle. Also state what type of a triangle is it.​

Answer 1

Answer:

third angle=80°

it is an acute angle triangle

Step-by-step explanation:

we know that the sum of all three angles of a triangle is 180° and here we have given two angles already

55°+45°=100°

hence 100 is the sum of these two angles now to find other angles wo will subtract 100 from 180°

180°-100°= 80°

hence the third angle is of 80°

and all the angles are less than 90° so it is an acute angle triangle
