PLZ HELP, I HAVE FREE POINTS IF WANTED The cruising speed of the bullet train will be no less than 150 miles per hour.

Use s to represent the train's cruising speed (in miles per hour).

AND

To ride a roller coaster, a visitor must be at least 52 inches tall.

Use h to represent the height (in inches) of a visitor able to ride.

m a t h w a y. c o m

step-by-step explanation:

c. side angle side. u shares the same sides

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
