Determine whether the Law of Cosines or the Law of Sines is needed to solve the triangle a = 11, b = 13, c = 7
Answers
Answer:
Step-by-step explanation:
Use the Law of Cosines:
c^2 = a^2 + b^2 - 2ab*cos C becomes
7^2 = 11^2 + 13^2 - 2(11)(13)cos C.
Once you have cos C, and then side c, you can use the Law of Sines to find the other two interior angles.

An eagle perched 40 ft up in a tree looks down at a 35 degree angle(angle of depression) and spots a vole. How far is the vole from the eagle(diagonal) to the nearest tenth of a foot?
Answers
Answer:
[tex]X=49ft[/tex]
Step-by-step explanation:
From the question we are told that:
Height of Eagle [tex]h=40ft[/tex]
Angle of depression [tex]\theta=35\textdegree[/tex]
Generally the trigonometry equation for diagonal X is mathematically given by
[tex]Cos\theta \textdegree=\frac{Adjacent}{Hypotenuse} }[/tex]
[tex]Cos\theta \textdegree=\frac{h}{X} }[/tex]
[tex]X=\frac{40}{Cos 35 } }[/tex]
[tex]X=48.83ft[/tex]
[tex]X=49ft[/tex]

How opd am I if 400 reduced by 2 times my age is 244?
Answers
Answer:
78
Step-by-step explanation:
x = your age
400 - 2x = 244
subtract 400 from both sides of the equation:
-2x = -156
divide both sides by -2:
x = 78
Answer: 78
Step-by-step explanation:
x = your age
400 - 2x = 244
subtract 400 from both sides of the equation:
-2x = -156
divide both sides by -2:
x = 78
Question 1
Which statement about the system of equations y = 3x + 9 and y = 3x – 4 is true?
A. No solution
B. Infinite solutions
C. Exactly one solution
D. Different y-intercepts so there are two solutions
Answers
Answer:
A. no solution
Step-by-step explanation:
y = 3x + 9
y = 3x - 4
Let's solve this.
We can see that both equations equal y, so we can set them equal to each other.
3x + 9 = 3x - 4
Combine like terms.
[add 4 to both sides]
3x + 13 = 3x
[subtract 3x from both sides]
13 = 0
This statement is not true; therefore, there is no solution.
If we look at the graph below, we can see the lines are parallel. Parallel lines will never intersect and have no solution in a system of equations.
