Sagot :
Y = 1st angle
X = 2nd angle
Y = 3X - 16
90 = X + Y
90 = X + (3X -16)
Do some algebra and X=26.5
So substitute x back in to find y, and Y=63.5
X = 2nd angle
Y = 3X - 16
90 = X + Y
90 = X + (3X -16)
Do some algebra and X=26.5
So substitute x back in to find y, and Y=63.5
Answer:
Two angles are supplementary one angle is 4 degrees less than three times the other find the measures of the angles
x + y = 180
x = 3y - 4
3y - 4 + y = 180
4y = 184
y = 46
x = 134
