Answer:
x= 40.33
Step-by-step explanation:
In geometry, alternate exterior angles are a pair of angles that are on the outer side of two parallel lines but on opposite sides of the transversal. In other words, they are the angles that are not on the same line as the parallel lines.
The alternate exterior angles are always equal in measure. This is because when a transversal intersects two parallel lines, it creates two pairs of alternate exterior angles, and each pair of angles is supplementary to each other (meaning that their measures add up to 180 degrees).
In this case:
a° = b°
Since,, the alternate exterior angles are always equal in measure.
3x+17 = 138
subtracting 17 on both sides
3x + 17-17 = 138-17
3x = 121
dividing both sides by 3.
The value of x is 40.33 which proves that r is parallel to s.
Answer:
c) 40.3
Step-by-step explanation:
According to the Alternate Exterior Angles Theorem, when two parallel lines are intersected by a transversal, the angles that are exterior to the parallel lines and on the alternate sides of the transversal are congruent.
Therefore, if lines r and s are parallel, then a° = b°.
To find the value of x that proves line r is parallel to line s, solve a° = b° for x.
Therefore, the value x that proves line r is parallel to line s is:
Calculate the density of an object with mass 45 grams and volume 25cm^3
Answer:
1.8g/cm^3
Step-by-step explanation:
Density = mass/volume
=> Density = 45/25
=> Density = 9/5
=> Density = 1.8 g/cm^3

Step-by-step explanation:
you take how many gigabytes (115) and divided it by the 30 days, giving you 3.833333333...
16 cm
4 cm
8 cm
answer: 8
Explanation:
Use the formula for the area of a circle:
A = π r 2
Here, the area is 16 π
16 π = π r 2
Divide both sides by
16 = r 2
Take the square root of both sides:
√ 16 = √ r 2
4 = r
Since the radius of the circle is
4
, the diameter is twice that:
d = 4 × 2 = 8
