Answer:

a) 180 degree

b) 180 degree

c) 180 degree

d) m∠3

e) m∠3

Step-by-step explanation:

a) We know that if two angles are supplementary then their sum = 180 degree.

In the given problem m∠1 and m∠2 are supplementary .Therefore m∠1+m∠2 =180°

b) We are given that m∠2 and m∠3 are supplementary. Therefore m∠2+m∠3 = 180°

c) m∠1+m∠2 = 180°

  m∠2+m∠3 = 180°

   equate equation 1 and equation 2:

   m∠1+m∠2=m∠2+m∠3

d)  m∠1+m∠2=m∠2+m∠3

    Subtract m∠2 from both sides

    m∠1+m∠2-m∠2=m∠2-m∠2+m∠3

     m∠1=m∠3

e)   m∠1≅m∠3 ....

Jorie leaves work 30 minutes late. She decides to make up time by taking the toll road instead of side streets. She can travel f
alexandr1967 [171]

Answer:

OPTION C

Step-by-step explanation:

We know that the toll road is 4 times faster than the side streets.

If 'x' represents the number of minutes she usually spend taking the side streets. The \frac{1}{4} x represents the time she takes taking the toll road.

Also we need to create an equation to represent her total travel time, including wait time. Therefore, the equation is:

y = \frac{1}{4}x + 30

Therefore, the correct solution is the OPTION C.
