Answer:
Step-by-step explanation:
See attachment for question illustration
From the attachment, we have:
Required
Solve d
First, we need to calculate <C
--- angles in a triangle
Make <C the subject
Next, we apply Sine's law to solve for d
In this case:
Make d the subject
<em>Hence, the base of the lake is approximately 340.7m</em>
Answer: b = 15, the perimeter is 40, and the area is 60.
Step-by-step explanation: First we need to find b. Using the Pythagorean Theorem, we know what 8^2 + b^2 = 17^2. This is the same as 64 + b^2 = 289. Subtract 64 from each side and we get b^2 = 225, which happens to be 15^2, so b=15. Now that we have b, we can add 8 + 15 + 17 to get the perimeter, 40. The area comes from 1/2*base*height, so 1/2 * 8 * 15. The area of the triangle is 60.
Answer:
600 ft in one minute
i don't know if my answer is correct or not
Step-by-step explanation:
Object 1 280 ft/min => 85 m/min => 85/60 m/sec
sim.
Object 2320 ft/min => 98 m/min => 98/60 m/sec
when two bodies move in opp. direction there speeds are added
so
resultant speed is object 1 + object 2
the resultant comes out as 183/60 m/sec
time is given 1 minute
and we know Distance = time * speed
distance = 183/60 * 60 (183/60 is the speed and 60 is the time in sec as 1 min. = 60sec)
so the distance comes out as 183 m
convert it into ft
1m = 3.2 ft
so 600 ft in one minute
The answer is the 5th one
The equation would be : 10y + 3x = 50
Hope this helps :)
