Quotient = 2
Solution:
Given expression is
.
To find the quotient.

In numerator 22 can be written as 2 × 11.

Take common term out in the numerator and denominator.

Common terms in the numerator and denominator will be cancelled.

Hence the quotient is 2.
Answer:
Given : s||t
Exterior sides in opposite rays : ∠5 and ∠7 are supplementary
Definition of supplementary angles : m∠5 + m∠7 = 180°
If lines are ||, corresponding angles are equal : m∠1 = m∠5
Substitution : m∠1 + m∠7 = 180°
Divide Numerator and Denominator by 5
3445 / 5 = 689
15 / 5 = 3
689/3
