Ok so cos(x) = sin(90-x) so using that you can get sin(7x-15) = sin(90-(3x+5)) so 7x-15 = -3x+85. 10x = 100 and x = 10. Use that to find the 2 angles are 55 and 35
Answer:
16x^2+40x+25
Step-by-step explanation:
Answer:
V₂=1061.85 ft³
Step-by-step explanation:
To determine where more wood is found, just find the volume of each log and see which one has the largest volume
knowing that the volume of a straight cylinder is
V=πR²h, where R=radius and h=height

As we can observe
V₂>V₁
Answer: 5.450 x 10^-4 x 3.550 x 10^-7
19.3475 x 10^-11
1.935 x 10^10
