Point o is the incenter of δabc.

what is mqbo?

mqbo is degrees.

Step-by-step explanation:

We have been given that point O is the in-center of triangle ABC. We are asked to find the measure of angle QBO.

We know that in-center of a triangle is the point, where three angle bisectors of triangle meet.

Since O is in-center, so AO will be angle bisector. We will find the value of x by equating the expression for angle QAO to angle SAO as:

Now we will substitute in the expression for measure of angle QBO.

Therefore, the measure of angle QBO is 12 degrees.

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
