Remark
I'm going to assume that it is just the 0.41 that is doing the repeating. If it is not leave me a note.
Solution
The trick is to call x = 3.4141414141 ....
then multiply by 100
100 x = 341.4141414141 ............ Now write the original decimal underneath.
<u>. . . x = 3.414141414141 ......</u>...... Subtract
99 x = 338 That's all that's left. The decimal part cancels out.
x = 338 / 99 Fractional answer.
x = 3 39/99
x = 3 13/33 If this isn't one of your answers, leave me a note.
Supplementary angles are angles that add up to 180 degrees.
180 = 3x + 4 + 8x + 11
Combine like terms.
180 = 11x + 15
Subtract 15 from both sides.
165 = 11x
Divide both sides by 11
15 = x
m<ABC = 3x + 4 = 3(15) + 4 = 45 + 4 = 49 degrees.
