Question

If the measure of two angles a the triangle is 47° and 52° respectively then find the measure of the third angle​

Answer 1

Answer:

3rd angle = 81°

Step-by-step explanation:

1st angle = 47°

2nd angle = 52°

3rd angle = x

Interior sum of triangle = 180°

47° + 52° + x = 180°

99° + x = 180°

x = 180° - 99°

x = 81°

Answer 2

81

Because:

• Sum of 3 angles = 180°
• 47 + 52 + c = 180
• 99 + c = 180
• c = 180 - 99
• = 81
