Answer:

Angle bisector

Step-by-step explanation:

Find the measure of the angle COA. By angle addition postulate,

m\angle COX=m\angle AOX+m\angle COA

From the diagram,

m\angle COX=80^{\circ}\\ \\m\angle AOX=40^{\circ},

then

80^{\circ}=m\angle COA+40^{\circ}\\ \\m\angle COA=80^{\circ}-40^{\circ}=40^{\circ}

Find the measure of the angle BOA. By angle addition postulate,

m\angle BOX=m\angle AOX+m\angle BOA

From the diagram,

m\angle BOX=60^{\circ}\\ \\m\angle AOX=40^{\circ},

then

60^{\circ}=m\angle BOA+40^{\circ}\\ \\m\angle BOA=60^{\circ}-40^{\circ}=20^{\circ}

Find the measure of the angle COB. By angle addition postulate,

m\angle COX=m\angle BOX+m\angle COB

From the diagram,

m\angle BOX=60^{\circ}\\ \\m\angle COX=80^{\circ},

then

80^{\circ}=m\angle COB+60^{\circ}\\ \\m\angle COB=80^{\circ}-60^{\circ}=20^{\circ}

This means, the measures of angles COB and BOA are the same and are equal half the measure of angle COA, so angles COB and BOA are congruent. This means, the ray OB is the angle bisector of angle COA

A silicon chip is 14 nanometers thick. A nanometer is equal to 0.000000001 meter. Express the thickness of the chip using scient
oksano4ka [1.4K]

Answer:

1.4 × 10^-8

Step-by-step explanation:

The chip is 14  nanometers

14 * .000000001

.000000014

Move the decimal 8 places to the right, because we need 1 number in front of the decimal for scientific notation.  The exponent will be -8 because  we moved it 8 places to the right

1.4 × 10^-8

1234 Maplewood Lane

Sunnydale, MN 55003

Dear Courtney,

   I hope you are doing well, and that your recent move to Sunnydale went smoothly. We all miss you greatly, but are excited for you to begin your new career in wildlife photography. I am writing to ask if you would consider writing a letter of reference for my application to the summer photography program at the local community college.

   When applying to the program, I immediately thought of you as a potential reference. As my former supervisor, you have directly observed my passion for photography, and my willingness to learn more about the field. I believe that my time working with you at the photography studio was an excellent first step towards my future career in the field. The letter of reference will enable me to continue my growth and experience in photography.

   I hope that you will consider writing the letter of reference, and I truly appreciate your consideration.

Regards,

Samantha Carlotta

What is the above an example of?
