Answer: 30° and 330°
<u>Step-by-step explanation:</u>
sec θ = 
sec θ = 
= 
cos θ = 
cos θ = 
cos θ = 
cos θ = 
Look at the Unit Circle to see that cos =
at 30° and 330° ( which is equivalent to π/6 and 11π/6)
Answer:
Step-by-step explanation:
3x+4y=29 .......(1)
6x+5y=43 .......(2)
Multiply equation (1) by 2
6x + 8y = 58......(3)
Substracting (2) from (3)
8y - 5y = 58 - 43
3y = 15
Dividing by 3
3y/3 = 15/3
y = 5
Substituting y = 5 into (2)
6x+5y=43
6x + 5(5) = 43
6x + 25 = 43
6x = 43 - 25
6x = 18
Dividing by 6
6x/6 = 18/6
x = 3
