Explain why the Leg-Leg (LL) theorem is the same as the Side-Angle-Side (SAS) postulate.
dexar [7]
Both claim that if the two legs (the sides of the right triangle which meet to form 90°) and one of the corresponding acute angles of two right triangles are congruent then the two right triangles are also congruent :) They say the same but in a slightly different way!

At 8:00 pm on Wednesday a friend in San Francisco, California (based on 120 degrees W) calls a friend in Miami, Florida (75 degr
____ [38]

Answer:

11:00 pm Wednesday

Step-by-step explanation:

Given

Current Time in San Francisco:

Time = 8:00pm\ (Wednesday) at 120 deg W

Required

Determine the current time at Miami at 75 deg W

First, we need to calculate the hours difference between San Franciso and Miami

Hours = 120\deg - 75\deg

Hours = 45\deg

Convert degrees to hours.

15\deg =1\ hour

So:

Hours = 45\deg

Hours = 3 * 15\deg

Hours = 3 * 1\ hour

Hours = 3\ hours

The above is the time difference between San Francisco and Miami;

The time in Miami is then calculated as:

Miami = 8:00pm + 3\ hours

Miami = 11:00pm

Hence, the time at Miami is: 11:00 pm Wednesday

If a train travels 80 m/s in two hours and 20 minutes, how far has it traveled?
Alexxx [7]

Answer:

distance = 585600 m

Step-by-step explanation:

change 2 hours 20 minutes to seconds

2  hrs * 60 minutes/1hr * 60 sec/min = 7200 sec

20 minutes * 60 sec/min = 120 sec

2 hr 20 min = 7320 seconds

distance = rate * time

distance = 80 m/s * 7320 s = 585600 m
