Please help me!! I really need help on this.

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label

Divide. write in the simplest form. 4 1/6 divided by 10

Two angles are complementary. the larger angle is 36 more than the smaller angle. what is the measure of the larger angle?
