Step-by-step explanation:
-1 + 3 = 2
Answer:
54
Step-by-step explanation:
3 times 18 = 54
6x=-5y
-5y=6x
so the answer is y=-6/5x
1+tan^2(y)=1/cos^2(y)
cos 2y -1=cos^2(y) -sin^2(y)-cos^2(y) -sin^2(y)
Area of the triangle:
A = 1/2 · c · b · sin A =
= 1/2 · 30 · 14 · 0.766 ≈ 160.87 ft²
Answer: 160.87 ft²
