Answer: The answer is C.

Step-by-step explanation: The triangle inequality theorem states that the two shortest sides when added must be larger than the largest side. Therefore, A is wrong because 4+5 < 10, B is wrong because 5 + 7 < 13, D is wrong because 4 + 5 < 10, but C is correct because 7 + 3 > 9.

Two angle of a tranigle measure 55 and 20 what is the measure of the third angle
wariber [46]

Answer:

105 degrees

Step-by-step explanation:

Recall that the sum of angles in a triangle is 180 degrees. As such, where a, b and c are the angles of a triangle then

a + b + c = 180 ( all in degrees)

Given that two angles of a triangle measure 55 and 20, let the size of gthe 3rd be T then

55 + 20 + T = 180

simplify

75 + T = 180

Subtract 75 from both sides

T = 180 - 75

T = 105
