GEOMETRY FIND ANGLES ALG
Angles are supplementary please find the angles for ABC(5x-5) XYZ(4x-3)
5x-3+4x-15=180 Combine Like Terms
9x-18=180 Add to both sides or make x single
9x=198 Divide
x=22
Plug-In
5(22)-5 Multiply
110-5 Combine like terms
105 Angle ABC
Do the same for the other angle
4(22)-3 Multiply
88-3 Combine like terms
85 Angle for XYZ
Check = 85+105 (add both angles, in this case, the problem does not have an answer soo use it for demonstration only)
Specific Equation won’t work but the steps are correct
Write Expression for the Following angles
Get the provided numbers well use (3x-5)
Then depending on what’s asked to find, plugin in the value
Remember Supplementary = 180
Complementary = 90
Let’s do complementary
Plugin the 90 with the given numbers
90-(3x-5) Make sure a negative is placed before
Distribute: 90-3x+5
Combine like terms 95-3x
Answer 95-3x
Do the same for supplementary angles
Find the Value for X
Two angles next to each other make a supplementary set
here are the numbers for both: 4x^2+120 and -2x^2=19x
Combine 2x^2+19x+120=180
subtract and add back. 2x^2+19x+120-120=180-120 is 2x^2+19x=60 then add back is 2x^2+19x-60
Then find factors using the x method or your personal method
You should get 24 and -5 Because 24*-5 = -120 and 24-5 = 19
Put 2 (the number before x or coefficient) below your factors
24/2 and -5/2
Simplify if possible soo x = 12 or -5/2
Then do the Pupster Maneuver 123 soo x = -12 or 5/2 (do this instead of spending even more lead on paper)
The answer is x=-12 or 5/2
Find the following values when not near angles
