On Tuesday, Emma's thermometer showed a temperature of -8 degrees when she woke up. The temperature then rose 1 degree every hour. Write an expression that represents the temperature change on Tuesday. Use the variables t for temperature and h for hours.

t = 1h - 8

Step-by-step explanation:

The temperature starts at -8 degrees and increases 1 degree every hour, meaning that the expression should be t = 1h - 8.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒
