Remark
You need to do some trig to get the final answer. There is no way around it. You can however, solve the first part with the Pythagorean Theorem.
Step One
Find AB
AB^2 = DB^2 + AD^2
AB^2 = 7.5^2 + 4.9^2
AB^2 = 56.25 + 24.01
AB^2 = 80.26
AB = sqrt(80.26)
AB = 8.9588
Step Two
Move to the triangle on your right. Find x
Tan(C)= opposite / adjacent
Tan(55.8) = AB/adjacent
Tan(55.8) = 8.9588/ x Multiply both sides by x
x * tan(55.8) = 8.9588 Divide by tan(55.8)
x = 8.9588/tan(55.8)
x = 6.09
Answer: A
Answer:
Option d
Step-by-step explanation:
The population of interest talks about the group that was research into or what type of participants, a research wants to draw a conclusion about.
The population of interest in this case study is all children within the ages of 5 and 15. A sample of 160 children were then drawn out from this total population.
Answer:
about 30.1 astronomical units or 4.5 billion kilometers.
Answer:
y = 12
Step-by-step explanation:
given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition x = 0.8 when y = 360, hence
k = yx =360 × 0.8 = 288
y = ← equation of variation
When x = 24, then
y = = 12
