Solve. Trigonometry using cosine, tangent and sine
Answer:
CD = 30.43; LK = 14.08
Step-by-step explanation:
Problem 12.
Let's first find BD. Triangle ADB is a right triangle with hypotenuse AB. By definition of sine ( or by theorem, they're equivalent) [tex]{BD \over 20} = sin 54.[/tex], hence BD= 16.18. Jump on the other side now. Triangle BDC is a right triangle with sides BD and CD. By definition of tangent [tex] {{16.18} \over CD} = tan 28 [/tex], thus CD= 30.43.
Problem 13
Assuming the 72° is angle JLK
As usual, triangle MJL is a right triangle with sides MJ and LJ. By definition of tangent [tex] {{JL} \over 14} = tan 51 [/tex]. Follows that JL = 14.81. Now, similarly, trinagle JLK is a right triangle, with hypotenuse JL. From the definition of sine, as before,[tex]{KL \over 14.81} = sin 72.[/tex]. Solving for the only unknown value, you find LK = 14.08.

A tractor can plant a field at a rate of 2.5 acres per 5 minutes. If a mammoth farm measuring 4 square miles needs planting, how long will it take in hours to plant the field? There are 640 acres in a square mile. Determine your answer to the nearest hour. If the tractor can run 8 hours a day, what is the minimum number of days it will take to plant the farm?
The time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.
The minimum number of days taken by the tractor when working 8 hours a day is 11 days.
What is the area?The area is the total surface occupied within the boundary of the figure.
How to solve the question?In the question, we are given that a tractor can plant a field at a rate of 2.5 acres per 5 minutes.
We are asked the time taken by the tractor to plant a field having an area of 4 square miles.
First, we convert the area of the field from sq. miles to acres using the conversion rate, 1 square mile = 640 acres,
Thus, the area of the field = 4 sq. miles = 4*640 acres = 2560 acres.
Time taken to plant 2.5 acres is given to be 5 minutes.
Thus, the time taken to plan 1 acre = 5/2.5 = 2 minutes.
Thus, the time taken to plant the field having an area of 2560 acres = 2560*2 minutes = 5120 minutes = 85.33 hours = 85 hours and 20 minutes.
Thus, the time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.
The time for which the tractor can run daily is 8 hours.
Thus, the number of days taken by the tractor to plant the field = 85.33/8 = 10.66625, or 11 days.
Thus, the minimum number of days taken by the tractor when working 8 hours a day is 11 days.

Answer:
large area: small area = 100:25 = 4:1
Step-by-step explanation:
Mid-Segment of a triangle is always parallel to the third side, and the length of the midsegment is half the length of the third side.
(x₁,y₁) (x₂,y₂) (x₃,y₃): A(-10,30), B(30,50, C(-40,20)
XY = 1/2 AC , YZ = 1/2 AB , ZX = 1/2 BC
X (10,40) , Y (-5,35) , Z (-25,25) : X(x'₁,y'₁), Y(x'₂,y'₂), Z(x'₃,y'₃)
area of triangle by 3 vertices: (x₁,y₁) (x₂,y₂) (x₃,y₃) is
a = abs[x₁(y₂-y₃)+x₂(y₃-y₁)+x₃(y₁-y₂)] / 2 ... this is just a common formula for any triangle
a = abs(-10*30 + 30*-10 + -40*-20) / 2 = 100
a' = abs(10*10 + -5*-15 + -25*5) / 2 = 25
a/a' = 100/25 = 4/1
X over 25 equals 35 over 14 solve for the missing variable

so 32÷4 + 8
2) quotient of 12 and 6 is 12/6
8 more than means + 8
so 12÷6 + 8
3) 7 * 4 + 3
here multiplication gets preference
so it is (7*4) + 3
3 more than the product of 7 and 4
4) 35 ÷ (12 - 5)
here parentheses gets preference
so it can be called as
35 divided by the difference of 12 and 5

If 20% of a number is 28 and 25% of the same number is 35, find 45% of that number.If 7% of a number equals 9, find 70% of that number.
Answer:
Step-by-step explanation:
Let the number be 'x'
20% * x = 28
[tex]\dfrac{20}{100}*x = 28\\\\\\\dfrac{1}{5}*x=28\\\\\\x=28*5\\\\x = 140[/tex]
[tex]\dfrac{45}{100}*140=9*7=63[/tex]
45% of 140 = 63
2)
[tex]\dfrac{7}{100}*y=9\\\\y=9*\dfrac{100}{7}=\dfrac{900}{7}=128.57[/tex]
[tex]\dfrac{70}{100}*128.57= 90[/tex]
for a field trip the school bought 47 sandwiches for $4.60 each and 39 bags of chips for $1.25 each.How much did the school spend in all?
Answer: To get to your final sum you will have to calculate the sum of both items: the sandwiches and the chips. Then you will get the total sum of all what they spend.
Step 1:
Sum of one sandwich= 4.60 dollar
sum of 47 sandwiches= 47×4.60 =216.2dollars
Step 2:
Sum of one chip=1.25 dollar
sum of 39 bags of chips=39×1.25= 48.75dollars
step 3: sum up the sum of sandwiches and that of the chips
216.2 + 48.75 =264.95dollars
