Answer:
can you explain it more and then I will know the answer
Answer:
x = 7
Step-by-step explanation:
2x + 8y=30
y=2
2x + 8(2) = 30
2x + 16 = 30
2x = 30 - 16
2x = 14
x = 14/2
x = 7
Cos θ = adjacent / hypothenus = 5/13
opposite = sqrt(hypothenus^2 - adjacent^2) = sqrt(13^2 - 5^2) = sqrt(169 - 25) = sqrt(144) = 12
sec θ = 1/cos θ = 1/(adjacent / hypothenus) = hypothenus / adjacent = 13/5
cot θ = 1/tan θ = 1/(opposite/adjacent) = adjacent / opposite = 5/12
sec θ = 13/5
cot θ = 5/12
