Answer:

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°

Answer:

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

HELLP PLSS<br><br><br>(-2 and 1/9) - (-4 and 1/3) = x<br><br><br>Find the value of x
dedylja [7]

Answer:

x = 20/9

Step-by-step explanation:

We want to write out all of the mixed fractions into improper fraction form. So -2 and 1/9 becomes -19/9 and -4 and 1/3 becomes -13/3. Then we get (-19/9) - (-13/3). The two minus signs together means a positive/plus sign, so we get -19/9 + 13/3. In order to add, we want the denominator to be the same. A common denominator could be 9, so -19/9 + 13(3)/3(3) = -19/9 + 39/9 = 20/9, which is our final answer

Hi can some please help meee
Olegator [25]

Answer:

M<2= 95° M<3=85° M<4=95°

Step-by-step explanation:

Remember that the angles could be either supplementary or congruent angles so since angle 2 and 1 are supplemental take 85 and subtract it from 180. So 2 =95 Now the congruent angle for angle 2 is 4 so 4=95. Applying the same property angle 1 is congruent to 3 so 3=85

Hope this helps!
