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

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
