We have that
sin ∅=-0.7660
the sin ∅ is negative
so
∅ belong to the III or IV quadrant
but
180°< ∅ < 270°
hence
∅ belong to the III quadrant
sin ∅=-0.7660
sin² ∅+cos² ∅=1
cos² ∅=1-sin² ∅------> cos² ∅=1-(0.7660)²-----> 0.4132
cos ∅=√0.4132-----> cos ∅=0.6428
the value of cos ∅ is negative-------> III quadrant
cos ∅=-0.6428
tan ∅=sin ∅/ cos ∅----> tan ∅=-0.7660/-0.6428----> tan ∅=1.1917
the answer is
tan ∅ is 1.1917
Simply divide 650/676=.9615 or 96.15%. So there was 3.85% error
Answer:
1.3 ft
Step-by-step explanation:
perimeter = 140/35 = 4 ft
diameter = 4 ft/ 3.14 = 1.3 ft
Every 30 min the tank fills up to 40 gallons
<span>The height of Gateway Arch shown on the Missouri quarter is 630 feet or 7,560 inches. Find how many 4 inch stacks of quarters make up the height of the Gateway Arch. If there are 58 quarter in 4 inch stack o, how many quarters high is the arch? </span>
<span>Hence to find how many 4 inch stacks of quarters make up the height of the </span><span>Gateway Arch,
Since the Gateway Arch is 7560 then for every stack is 4 inches to find the stacks all in all, we just have to divide 7560 / 4 = 1890
Then, to find </span><span>how many quarters high is the arch,
58 quarter x 4 inch = 232 quarters high in inches.
