The temperature is -2∘c. if the temperature rises by 15∘c, what is the new temperature?

The new temperature value if an initial temperature value of - 2°C rises by 15°C will be 13°C

Using the addition operation :

Final temperature = Initial temperature + Final temperature

Final temperature = (-2°C + 15°C) = 13°C

Therefore, the final temperature is 13°C

13 Degrees Celsius, or 55.4 degrees Fahrenheit.

-2 + 15 = 13. To find your answer in Fahrenheit, just do (Celsius here) x 9/5 + 32.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
