The measures of the three interior angles of a triangle are 50degrees, 55degrees and x degrees. What is the degree measure of the largest interior angle of this triangle?

3rd angle of a triangle = x = 75°

Step-by-step explanation:

1st angle of a triangle = 50°

2nd angle of a triangle = 55°

3rd angle of a triangle = x = ?

We know that sum of three angle of triangle = 180°

1st angle of a triangle + 2nd angle of a triangle + 3rd angle of a triangle = 180°

50° + 55° + x = 180°

105° + x = 180°

x = 180° - 105°

x = 75°

3rd angle of a triangle = x = 75°

75

Step-by-step explanation:

The three angles of a triangle add to 180 degrees

50+55+x = 180

Combine like terms

105+x = 180

Subtract 105 from each side

105-105+x = 180-105

x = 75

The largest angle is 75

-14 is the answer

hope this : ))

160
