Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of angle ∠QBO

we know that

The incenter of a triangle is the intersection of its interior angle bisectors

so

we have

---> given problem

so

step 2  

Find the measure of angle ∠QOB

we know that

In the right triangle QOB

---> by complementary angles

we have

substitute

cut 138 centimeters off

step-by-step explanation:

250-112 = 138
