A
Step-by-step explanation:
Answer:
111.4 degrees
Step-by-step explanation:
Let's write cos x = -0.3646. Or, look up the symbols chart at the bottom of your page and click on Ф to obtain this character: cos Ф = -0.3646.
If Ф is in Quadrant III, then the adjacent side is negative and the hypotenuse is positive.
-1
Type this into your calculator: cos -0.3646. Result: 1.934 (radians)
This converts to degrees as follows:
1.934 rad 180 degr
--------------- * --------------- = 111.4 degrees. Note that this angle is in QIII.
1 π rad
Okay so let’s start with number one you have 2 out of the 3 sides and you have to solve for the third
Let’s call the side you are looking for side A than the side with 13 side B and the side with 29 side C
So
B=13
C=29
A= ?
You would use the equation
A^2 + B^2 = C^2
So
A^2 + (13)^2 = (29)^2
13^2 = 169
29^2 = 841
So
A^2 + 169 = 841
A^2 = 672
A= 4 times the square root of 42
Or if yu need a estimated answer
A= 25.9
One solution- if the graphs of the equations intersect, then there is one solution that is true for both solutions.
No solutions- If the graphs of the equation do not intersect (example-if they are parallel) there are no solutions that there are true for both equations.
