sina Question 3 Determine the value of each of the following by using a calculator. Answers should be given correct to 3 decimal places. A = 112,4° and B = 48,6° 3.1 (2) 2 3.2 sin(A-B) (2) 3.3 sinA + 2cosB 3.4 COS2A -- sine [10] (3) (3)​

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

i think the amount would be $140.62

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
