Point D is rotated 180 degrees using B as the center. Explain why the image of D must lie on the ray BA.
Igoryamba

Answer:

The image of D must lie on the ray BA, since ray BA is antiparallel to ray BD. That is, the angle between both rays is 180 degrees.

Step-by-step explanation:

Let be D' the image of D such that D is rotated 180 degrees counterclockwise with B as center of rotation.

D' must lie on the ray BA, since ray BA is antiparallel to ray BD. That is, the angle between both rays is 180 degrees.

In triangle $ABC,$ $AB = BC = 17$ and $AC = 16.$ Find the circumradius of triangle $ABC.$
sweet-ann [11.9K]

Answer:

R = 9.63\ units

Step-by-step explanation:

Given

AB = BC = 17

AC = 16

Required

Determine the circumradius, R

The circumradius is calculated as follows;

R = \frac{AB * BC * AC}{\sqrt{(AB + BC + AC)(AB + BC - AC)(AB + AC - BC)(AC + BC - AB)}}

Substitute the values of AB, BC and AC

R = \frac{17 * 17 * 16}{\sqrt{(17 + 17 + 16)(17 + 17 - 16)(17 + 16 - 17)(16 + 17 - 17)}}

Evaluate the denominator

R = \frac{17 * 17 * 16}{\sqrt{(50)(18)(16)(16)}}

R = \frac{4624}{\sqrt{230400}}

Take square root of 230400

R = \frac{4624}{480}

R = 9.63\ units <em>(Approximated)</em>

<em>Hence, the circumradius is 9.63</em>

Write True or False. The transformation is a reflection.<br> True<br> or False
Jet001 [13]

Answer:

False

Step-by-step explanation:

This transformation is a rotation. If it were a reflection the moon shape would be at a 180 degree flip but instead is at a 90 degree rotation.

Hope this helped!

What does a supplementary angle look like
Keith_Richards [23]

Answer:

It has no special appearance.

Step-by-step explanation:

Any angle of measure 180° or less is supplementary to some angle. A supplementary angle is one that is the difference between 180° and the angle you have. That is, two supplementary angles total 180°.

__

Supplementary angles are readily identifiable in a number of geometries. Adjacent angles of a parallelogram are supplementary; linear angles are supplementary. Same-side interior angles where a transversal crosses parallel lines are supplementary.
