Answer:

45° (if you need to also find x, it's 22)

Step-by-step explanation:

First of all, you need to remember that all triangles are equal to 180°. By examining the triangle, you already know two of the angles: 45° and 90° (you can tell it is a right triangle because of the box in the bottom-right corner). Since you have two of the three angles, you can deduce that the unknown angle is 45° (45 + 90 + <u>45</u> = 180).

(Just in case you need to also find x, just write it as an equation and solve for x.)

  1. 2x + 1 = 45
  2. 2x = 44
  3. x = 22

Hope this helps!!!❤️

2x+1 = 45
2x=44
X=22
The angle measure of 2x+1 is 45

After traveling exactly half of its journey from station A to station B, a train was held up for 10 minutes. In order to arrive
Alex17521 [72]
Let's define variables:
 s = original speed
 s + 12 = faster speed
 The time for the half of the route is:
 60 / s
 The time for the second half of the route is:
 60 / (s + 12)
 The equation for the time of the trip is:
 60 / s + 60 / (s + 12) + 1/6 = 120 / s
 Where,
 1/6: held up for 10 minutes (in hours).
 Rewriting the equation we have:
 6s (60) + s (s + 12) = 60 * 6 (s + 12)
 360s + s ^ 2 + 12s = 360s + 4320
 s ^ 2 + 12s = 4320
 s ^ 2 + 12s - 4320 = 0
 We factor the equation:
 (s + 72) (s-60) = 0
 We take the positive root so that the problem makes physical sense.
 s = 60 Km / h
 Answer:
 
The original speed of the train before it was held up is:
 
s = 60 Km / h

Roderick is counting the change on his dresser. he has twice as many pennies as he does dimes. he has twice the amount of dimes
melamori03 [73]
P = 2d
d = 2n.....n = 1/2d
q = d - 3

since dimes is mentioned in relation to  quarters, pennies, and the nickels, u would use d as ur variable

ur expression would be : d + (2d) + (1/2d) + (d - 3) = total amount of coins...then u would solve for d, the number of dimes. And once u know that, u can sub that answer back into ur original equations to find the number of pennies, quarters and nickels
