Work out the size of angle y.

y = 38

Step-by-step explanation:

exterior angle of a triangle = sum of its interior opposite angles

129 = 91 + y

y = 129 - 91

y = 38

y = 38°

Step-by-step explanation:

y + 91° = 129° (opp. ∠s = ext. ∠)

y = 129° - 91°

y = 38°

In a triangle, the two opposite angles of an angle equals to the exterior angle that is adjacent to that angle on a straight line.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
