Answer 1

sorry sorry sorry sorry sorry sorry sorry sorry sorry

Answer 2

Answer:

• the measure of third angle is 44°

Step-by-step explanation:

it is given that 1st angle of the triangle is 72°

and 2nd angle of the triangle is 64°

so,

let the third angle be "x"

We know that sum of all angles of a triangle is 180°

ie 72°+64°+x=180°

solving 72°+64°+x=180°further

=72°+64°+x=180°

136°+x=180°

x=180°-136°

x= 44°

the measure of third angle is 44°
