Question

Give me answer than follow you frist give me answer​

Answer 1

Step-by-step explanation:

let the third angle be x

x + 47 +52=180(sum of angles of a triangle is 180)

x + 99=180

x=180-99=81

Answer 2

Answer:

81°

Step by Step:

the measure of 1st angle =47°

the measure of 2nd angle=52°

The sum of angles of a triangle =180°

then 3rd angle =180°-99°

=81°

(check: 47°+52°+81°=180°)

Therefore 3rd angle of triangle=180°.
