Help me with this question

65, 90, 30, 24(in order abcd)

Step-by-step explanation:

The sum of all angles in a triangle is 180 degrees, so knowing this, you should be able to get all of them.

1) x+65+50 = 180, so x= 65

2)x+34+56 =180, so x= 90

3)90+3x=180, so x=30

4)90+66+x=180, x=24

a) 165

b) 90

c) 45

d) 34

900 degrees
