Which does NOT represent an obtuse angle
Darya [45]
Hey there!

An obtuse angle is defined as an angle that is wider than 90° but less than 180°. For example, a 68° would not be considered obtuse, but a 107° would. As long as the degree is between 90 and 180, the angle is obtuse. Any other angle (either between 0 and 90 OR 180 and 360) is not obtuse. 

You can use this information to answer the question based on the angles you have been given. 

Hope this helped you out! :-)

J = K (1+ p/100) make p as a subject
olganol [36]

Answer:

p = 100(J/K - 1)

Step-by-step explanation:

When we want to make a variable the subject of an equation, we want to get that variable by itself on one side of the equation - to unwrap it from all the operations attached to it.

Here's what the process looks like for p:

J=K(1+p/100)\\J/K=1+p/100\\J/K-1=p/100\\p=100(J/K-1)
