Two angles are supplementary , If one angle is 60⁰, then measure of another angle is : *
Answers
Step-by-step explanation:
Two angles are supplementry when they add up to 180° (Very important point)
One angle is given 60°
Let the other angle be x
According to the question
60+x=180
x=120°
Therefore the other angle is 120°

Step-by-step explanation:
The first angle's measure would be
30
o
while the second angle would be
150
o
.
Explanation:
Let us say angle 1 is
x
and angle 2 is
y
. We know that
x
+
y
=
180
. We can also say
y
is the angle that is 3 times
x
+ 60. We get
y
=
3
x
+
60
. We can know plug this in for
y
getting
x
+
3
x
+
60
=
180
. Combining like terms gets us
4
x
+
60
=
180
. We then subtract 60 on both sides, and we get
4
x
=
120
. We then divide 4 on both sides,
4
x
4
=
120
4
, and 4 is cancelled out next to
x
and 120 divided by 4 is 30. The first angle is now solved and equals 30. We then go back to out equation of
y
=
3
x
+
60
and we plug in 30 for
x
. 3(30) equals 90, and 90 + 60 equals 150. The second angle is now solved for.
