5/tan(30)
Answer:
equilateral triangle all angles add up to 180 and are equal so each angle is 60 degrees
angles on a line add up to 180.
angle CBD = 180-60 = 120
DBC is an isosceles triangle so it's base angles are the same.
180-120= 60
60/2=30
Answer:
its c or #3
Step-by-step explanation:
Answer:
approx. 1/2
part B: 11/24
1/24, explanation in step by step
Step-by-step explanation:
10 /12 is close to 1
3/8 is close to 1/2
Part B:
10/12 - 3/8
10/12 = 20 /24
3/8 = 9/24
20/24 - 9/24 = 11/24
1-1/2=1/2
Part C:
1/2 - 11/24 = 12/24 - 11/24 = 1/24
I think my answer is reasonable because when I subtracted my answer from my estimate, I got a number very close to 0
this is the simplest form
