825 miles because 495 divided by 9 is 55 so 55=1 mile and 15 miles=825
Answer:
A
Step-by-step explanation:
complementary angles are 90 degrees so if we add both angles together we get 90 degrees. the equation is x-3+x+5=90. then we do algebra and so it goes to x-3+x=85 then to x+x=88 then to 2x = 88 then to x = 44. now we just do 44+5=49 44-3=41
For a vector:
cos^2(α) + cos^2(β) + cos^2(γ) = 1
From the givens:
α = π/4, therefore, cos(α) = 1/root 2 and cos^2(<span>α) = 1/2
</span>β = π/3, therefore, cos(β) = 1/2 and cos^2(<span>β) = 1/4
Substitute in the above equation:
1/2 + 1/4 + </span>cos^2(γ) = 1
cos^2(γ) = 1 - 1/2 - 1/4
cos^2(γ) = 1/4
cos(γ) is either 1/2 or -1/2
For cos(γ)= 1/2 .......> γ = <span>π/3
For </span>cos(γ)= -1/2 .......> γ = 2π/3
