Answer:
5 SHOULD BE THE ANSWER SORRY FOR ALL CAPS
Answer:1/2 y
Step-by-step explanation:
We can solve this using ration reasoning:
x
2
x
1
=
y
2
y
1
Explanation:
If
x
varies directly with
y
(written
x
∝
y
), then doubling
y
means doubling
x
, so the rations of final values and initial values will be the same:
x
2
x
1
=
y
2
y
1
In this case,
x
2
9
=
24
18
x
2
=
9
⋅
24
18
=
12
Or, intuitively, if
x
∝
y
and
x
=
9
when
y
=
18
, we can conclude that
x
=
1
2
y
and
1
2
of 24 is 12.
The answer is A. 3° 87+90= 177+ 3= 180°
Answer:
The sum of a° and b° will be 180°.
Step-by-step explanation:
We know that two angles are supplementary when they add up to 180 degrees.
We also know that we know that a straight angle is said to be having 180 degrees. A straight angle does change the direction to point the opposite way.
i.e.
Straight angle = 180°
For example, a flat surface does have an angle of 180 degrees. Also, a straight stick does have a straight angle or 180 degree.
So, from the figure, the sum of a° and b° will be 180° as they add up to 180 degrees on a straight line and hence a° and b° are supplementary angles.
Therefore, the sum of a° and b° will be 180°.
