What is QS 2 units 5 units 17 units 33 units
1 answer:
Applying the perpendicular bisector theorem, the length of QS is: C. 17 units.
<h3>What is the Perpendicular Bisector Theorem?</h3>According to the perpendicular bisector theorem, any point on a perpendicular bisector is said to be the same distance from both endpoints of the line form which both were drawn on.
Applying the perpendicular bisector theorem, we have:
3x + 2 = 5x - 8
3x - 5x = -2 - 8
-2x = -10
x = -10/-2
x = 5
QS = 5x - 8 = 5(5) - 8
QS = 17 units

Answer:
The absolute error of the measurement is 0.25 inches
Step-by-step explanation:
we know that
The absolute error of a measurement is equal to one half the unit of measure.
In this problem we have
7.5 inches
The measurement is given by 0.5 inches
So
the absolute error of this measurement is
Therefore
the exact measurement could be between
7.5 (+/-) 0.25 in
That is, between 7.25 in and 7.75 in
Answer:
Step-by-step explanation:
To copy an angle we follow the following steps,
1). Draw a working line with the help of a straightedge.
2). Now we put a point S as the vertex of the angle.
3). Construct an arc with a radius 'r' (any length ) from vertex S which intersects the working line say at V.
4). With the same radius we draw an arc from point E which intersects the line ED and EF at G and H respectively.
5). Mark an arc from point G which intersects line EF at I.
6). Measure the distance between points G and I with compass and mark an arc from point V which intersects the previous arc say at U.
7). Now join the points S and U.
Hence we copy any angle.
