Answer 2
Step-by-step explanation:
the number are being added together based on their position
Answer:
9.42 m
Step-by-step explanation:
Arc AB = 2πr x (45/360)
= (2 x 3.14 x 12) / 8
= 9.42
For number 7.
Supplementary angles sum to 180.
2x+4x=180
6x=180
x=30
The two angles are 2x and 4x or 60 and 120
A = 9/10
b = 1/3
c = 2/3
I dunno how to explain it properly but the question gives the fractions, you just need to find out what makes the other fraction that can equal to 10/10 for the first part, then 3/3 for the second part.
