A triangle has two angles measuring 73 and 67. Determine the measure of the third angle please help

Step-by-step explanation:

  Measure of one angle of the triangle is given to be 42

Measure of second angle of the triangle is given to be 73

Let the measure of the third angle of the triangle be x

Now, By using the angles sum property of a triangle, We have :

Sum of all the three angles of a triangle is always supplementary

⇒ ∠1 + ∠2 + ∠3 = 180°

⇒ 42° + 73° + ∠3 = 180°

⇒ 115° + ∠3 = 180°

⇒ ∠3 = 180° - 115°

⇒ ∠3 = 65°

Hence, The measure of third angle of the triangle is 65° its actually  42 is the answer

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
