Answer:
Step-by-step explanation:
<u>Let the numbers are:</u>
- x, x + 1, x + 2, x + 3 and x + 4
- Their sum is 5x + 10
- Their mean is (5x + 10)/2 = x + 2
If we swap the digits on the largest number, the sum increases by 1 more than x + 2
<u>We are looking for the number x + 4 = ab such that:</u>
- ba - ab = ab - 2 + 1
- ba = 2ab - 1
- 10b + a = 2(10a + b) - 1
- 10b + a = 20a + 2b - 1
- 8b = 19a - 1
- 19a = 8b + 1
<u>By trial method we get the solution:</u>
<u>Since x + 4 = 37, the lowest number is:</u>
<u>Lets verify:</u>
<u>The sum is:</u>
<u>The mean is:</u>
<u>Change the largest number tp 73 and find the sum again:</u>
- 175 + (73 - 37) = 175 + 36 = 175 + 35 + 1
The sum has increased by 1 more than 35
Answer: W is 29. Add 8 and 21 you get 29
Step-by-step explanation:
Answer:
as you can see in both triangles, comparing to each other, x = 90 angle
w = 52, because when 90 + 38 + w = 180 for a triangle
z=10yd
u = 62yd
v = 79 yd
please, also make sure these answers are correct from anyone, but ihave answer correct :)
Hope it helps
It’s correct answer believe me
56
360-248=112
inscribed angle so 112/2=56
