Top angle = 180-112 = 68
Bottom angle = 180 - 126 = 54
Sum of angles in a triangle = 180 sooo
68+54+m=180
122+m=180
m=180-122
m=58
Therefore, angle m = 58

Answer:
a:b = 3:5
Step-by-step explanation:
As a:b is required, divide both terms by b
5a:b + 3b:b = 6b:b
5a:b + 3 = 6
5a:b = 6 - 3
5a:b = 3
a:b = 3:5
4 x² + 6 = 40
4 x² + 6 - 6 = 40 - 6
4 x² = 34
x² = 34 : 4
x² = 8.5
x = √ (8.5)
x 1 = 2.9154759 ≈ 2.92 ( to the nearest hundredth )
x 2 ≈ - 2.92
Answer:The solutions are approximately 2.92 and - 2.92.
