2.8 hours because 3.5 divided by 1.25 is 2.8
Answer:
I think complementary angles
Answer:
I'm guessing it is 3x(9x20)=3x180=540
Step-by-step explanation:
Answer:
y=63, x=20, x=47, b=70, c=89, x=133
Step-by-step explanation:
1) y=63- alternate angles are the same
2) 4x+5x=180
9x=180
x=20
3) x=47
4) b=70- angles on a line equal to 180
c=89- angles in a triangle add up to 180
5) x=133- angles that are alternate are the same
