Step-by-step explanation:
Given.:
m<4 = 2x°
m<5 = 4x°
Required:
Value of x
Solution:
<4 and <5 are angles in a straight line, therefore:
m<4 + m<5 = 180°
Substitute
2x + 4x = 180°
6x = 180°
x = 180/60
x = 30
Sometimes because the answer be be a positive, and the opposite would be a negative which is less. But for a negative, it is always greater. So the answer is sometimes will be greater than the number itself.
