Answer:

A) x=40°

B) They have the same lengths.

Step-by-step explanation:

Since it is an isosceles triangle, both sides are the same. So if you add up all the angles of any triangle, it should always add up to 180°. There is a 50° angle and a right angle (90°) so you subtract 50 and 90 from 180 (180-50-90) and you get 40. X has to be 40° :)

The result of our calculations about the rate and time are:

  • r=d/t
  • 200000m/hr
  • 200km/hr
  • km/hr

<h3>What is rate?</h3>

Rate can be regarded as the given object with respect to time.

falcon flies= 800,000 meters

t= 4 hours

We were given the  formula as (d = rt)

d= distance

r = rate

t = time

We can make our calculations as:

part a:

r=d/t

part b:

falcon's rate in meters per hour = 800,000 meters / 4 hours = 200000m/hr

part c:

falcon's rate in kilometers per hour=(200000m/hr *(1/1000)=200km/hr

part d:

km/hr

The expression below is the factorization of what trinomial?
Lapatulllka [165]
The answer is:  [A]:   45x² + 81x + 36 .
_________________________

Explanation:  Use "FOIL" technique: (First, Outer, Inner, and Last Terms); 
                       then, combine the "like terms", to simplify. 
__________________________________________

(5x+4)(9x+9) = 45x² + 45x + 36x + 35 = 45x² + 81x + 36 .
                                                                       (which is answer choice: "A".).
