Answer:
100°= angle b(VERTICAL OPPOSITE ANGLE)
100°+x°=180°[co interior angle]
x=180°-100°
x=80°
For the first one:
The radian of 60º is 1.047. you just have to find one that has the same value, which would be
/3. (the last choice).
for the second one:
you do it the other way. The answer is 45 degrees.
X/-9 ≥3 multiply both side by -9 to get rid of fraction
-9/1•x/-9 ≥-9•3
Cross cancel -9 on left side
x ≥ -27
