Answer: the distance between him and his friend is 218.39 feet
Explanation:
Given the data in the question;
FROM IMAGE A;
distance travelled in minute and a half
⇒ (60 + 30)sec × 4ft/sec = 360 fts
FROM IMAGE B
tan35°= h/x --- equ 1
and tan36° = h/(360 - x), so h = (360 - x)tan36°
we substitute value of h into euq 1
tan35° = (360 - x)tan36°/x
xtan35° = (360 - x)tan36°
0.7002x = 261.5553 - 0.7265x
0.7002x + 0.7265x = 261.5553
1.4267x = 261.5553
x = 183.32 feet
so
360 - x ⇒ ( 360 - 183.32) = 176.68
FROM IMAGE C
Let the distance between them be d
so
cos36° = 176.68 / d
dcos36° = 176.68
d = 176.68 / 0.809
d = 218.39 feet
Therefore the distance between him and his friend is 218.39 feet
The answer is A.) subduction
Rosalind Franklin, James Watson, and Francis Crick’s discovered the DNA's Double Helix.
<h3>What is DNA?</h3>
DNA is an abbreviation for deoxyribonucleic acid and it can be defined as the molecules that are found within cells, and they are saddled with the responsibility of storing genetic information in living organisms.
In 1953, James Watson and Francis Crick's used other scientists' work to create a model of DNA in that they used Rosalind Franklin's photo to help them determine that deoxyribonucleic acid (DNA) was a double helix.
Furthermore, the discovery of DNA's Double Helix by Rosalind Franklin, James Watson, and Francis Crick led to modern molecular biology, which has helped many scientists and researcher to understand how genes control the chemical processes in the body of a living organism.
