Subtract four from both sides. That'll put both numbers without a variable on one side, and the number with the variable is by itself.
Answer:
y = 148°
Step-by-step explanation:
4x - 18 = 2x + 12 (alternate exterior angles are congruent)
Collect like terms
4x - 18 = 2x + 12
4x - 2x = 18 + 12
2x = 20
Divide both sides by 2
x = 10
y = 180 - (2x + 12) (linear pair theorem)
Plug in the value of x
y = 180 - (2(10) + 12)
y = 180 - (20 + 12)
y = 148°

Answer:
145
Step-by-step explanation:
In this geometry, the central angle (x°) and the external angle (35°) are supplementary.
x° = 180° -35°
x = 145
Answer:
Give me the side lengths or we have a problem
Step-by-step explanation:
Let x = The age of Michael
Let 2x-3 = The age of Michaels cousin
X+2x-3=46
x=16+1/3
X = 49 years
I think that’s the answer I’m not 100% sure though
