Find the unknown for every letter

x = 70°, y = 110°, z = 70°

Step-by-step explanation:

The two straight lines are intersection each other.

y = 110°  [justification vertical angles, or vertically opposite angles]

x + 110° = 180  [supplementary angles]

therefore x = 180-110 = 70°

Similarly,

z + 110° = 180  [supplementary angles]

therefore z = 180-110 = 70°

Y= 110°

Z= 70°

X= Z, which is 70°

Step-by-step explanation:

Because 110° is same to y, y=110°.

A 180° angle is a straight line, so 180-110=70.

Thus, z is 70°

Because x is same to z, it is 70° too.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
