Answer: question no. 1 -a. yes, the sides are in the ratio 2 : 5.question no. 2 -b. 59°question no. 3 -c. angles x and y are remote interior angles.question no. 4 -d. 90°, 45° and 45°question no. 5 -b. mn and qrstep-by-step explanation: question no. 1 -rs : xu = 3 : 7.5 = 2 : 5rt : x? = 6.4 : 16 = 2 : 5st : u? = 6 : 15 = 2 : 5as the ratios of all sides are equivalent, the triangles must be congruent and the sides must be proportional.therefore, the answer is: a. yes, the sides are in the ratio 2 : 5.question no. 2 -in the second diagram, angle b is the only letter not shown. therefore, the number must be equivalent to angle b.if we substitute the value of angle b as being 22° in the first diagram, we can now use the angle sum of a triangle to obtain the value of angle a.angle sum of a triangle = 180°therefore: let angle a = aa + 99 + 22 = 180a = 180 - 99 - 22a = 59°therefore, the answer is: b. 59°question no. 3 -angles x and y don't share the vertex of the triangle with the exterior angle w. remote interior angles don't share a vertex of a triangle with an exterior angle. this means that angles x and y are remote interior angles.therefore, the answer is: c. angles x and y are remote interior angles.question no. 4 -the sum of all interior angles of a triangle must be equivalent to 180°.90°, 45° and 45° are the only set of angle measures that are equivalent to 180°.therefore, the answer is: d. 90°, 45° and 45°question no. 5 -the only pair of sides stated in the options which are corresponding are mn and qr.therefore, the answer is: b. mn and qr.

Given:

The points 7 and -7.

Required:

We need to find the distance between 7 and -7 by using absolute values.

Explanation:

1)

We need to subtract the given numbers to find the distance.

Subtract 7 from -7 and take absolutely to find the distance.      The absolute value of a number is never negative.

The distance is non-negative. so absolute values help to avoid the negative values for distance since the absolute value of a number is never negative.

2)

Subtract 5 from -5 and take absolutely to find the distance.     The distance is non-negative. so absolute values help to avoid the negative values for distance since the absolute value of a number is never negative

3)

Subtract 2 from -2 and take absolutely to find the distance.   The distance is non-negative. so absolute values help to avoid the negative values for distance since the absolute value of a number is never negative

Final

1)

The absolute value of the difference between 7 and -7 is 14.

The distance is non-negative. so absolute values help to avoid the negative values for distance since the absolute value of a number is never negative.

2)

The absolute value of the difference between 5 and -5 is 10.

The distance is non-negative. so absolute values help to avoid the negative values for distance since the absolute value of a number is never negative.

3)

The absolute value of the difference between 2 and -2 is 4.

The distance is non-negative. so absolute values help to avoid the negative values for distance since the absolute value of a number is never negative.  ### Other questions on the subject: Mathematics
