Answer:
Step-by-step explanation:
Let the angles be 4x , 5x
4x + 5x = 180 { supplementary}
9x = 180
x = 180/9
x = 20
Larger angle= 5x = 5* 20 = 100
Answer:it’s A
Step-by-step explanation:
By making the surface rougher and to increase the force pushing the surfaces together.
Divide f(x) by x + 15
this comes to 2x^2 - 6 which represents the length
