Answer:
1) 92,22,66
2) 106,13,61
3) 87,34, 59
4)20,74,86
Explanation:
1) Let the unknown angle be x
92 + 22 + x= 180( Sum of angles in a triangle )
114+ x = 180
x= 180-114
=66
2) 106+ 13 + x =180
119 +x = 180
x= 180-119
x= 61
3) 59+34 +x = 180
93+x = 180
x= 180-93
=87
4) 86+74 +x=180
160 +x =180
x= 180-160
=20
