Question

Which of the following can be the angles of a triangle? *
1 point
(100 , 70, 30) degrees
(90 , 45, 45) degrees
(85, 25, 100) degrees
(120, 60,40) degrees

Answer 1

It has to be ( 90,45,45 ) degrees.

Answer 2

Answer:

(90 , 45, 45) degrees

Step-by-step explanation:

Sum of all angles of triangle =  180

for (100 , 70, 30) degrees   => 100+70+30 = 200 ≠ 180

(90 , 45, 45) degrees          => 90 + 45 +45 = 180  

(85, 25, 100) degrees         => 85 + 25 +100 = 210 ≠ 180

(120, 60,40) degrees          => 120 + 60 + 40 = 220 ≠ 180
