The peak of the mountain is 3 miles
above where the chair lift drops skiers
off. The chair lift travels 2 miles up from
the bottom of the mountain. If the point
where the lift drops the skiers off is
represented by zero, what integer would
represent the bottom of the mountain?
What integer would represent the top of
che mountain?

Answers

Answer 1

Answer:

Bottom= -2

Top= 3

Step-by-step explanation:

Since the bottom is 2 miles below the chair lift, you'd do 0-2 to get -2.

If the chair lift is 0 and we know the peak is 3 miles above it, you would add 3+0 to get 3.

Answer 2
The bottom would be -2 and the top 3. Hope this helps!!

Find the measure of the missing angles.
X=
Y=
Z=

Answers

Answer:

X= 41

Y= 90

Z= 41

Step-by-step explanation:

X=Z

Y+49=139

Z+Y+49=180

X+139=180

139+49+X+Z+Y=180

These we know because of the placement of the angles.

Using this information, we can solve this in numerous ways. I'm going to solve it using one of them. Making both sides equal to 180 and then checking my work by adding all of the numbers I get together to make sure that they equal 360.

X+139=180

X=41

X=Z.

49+Z+Y=180

49+41+Y=180

90+Y=180

Y=90

Thus,

X= 41

Y= 90

Z= 41

To check, let's add them all together.

41+90+41+139+49=

360

This is correct!

X=41
Y=90
Z=41
