Answer:20.096
Step-by-step explanation:
radius =r=4
Φ=288
π=3 14
Length of arc=Φ/360 x 2 x π x r
Length of arc=288/360 x 2 x 3.14 x 4
Length of arc=0.8 x 2 x 3.14 x 4
Length of arc=20.096
Answer:
The answer is

Step-by-step explanation:
The problem is

First we have to bring x to the other side se we subtract x from both sides

Then we have to put it in order so the answer is

Answer:C
Step-by-step explanation:
180-(60+40)=80°
C=80°
20/sin80. =a/sin40
a=(20sin40)÷sin80
=13.1
