PLS Help

Answer 1

Answer:

141 °

Step-by-step explanation:

the given figure is a traingle

let the unknown angles be x

therefore the three angles are

15° , 25° and x + 39°

now by applying angle sum property of a traingles which states that sum of all the angles of a traingle is 180°

thus,

15° + 39° + x + 25° = 180°

40° + x + 39° = 180°

x + 39° = 140°

x = 141°
