Answer:
x = 7
Step-by-step explanation:
2x + 11 = 25
subtract 11
2x = 14
divide by two
x = 7
First: let’s get Ben’s current age:
16+4=20
Next let’s get Dunn’s current age:
4/7=20/x
Cross multiply and divide:
x=35
Let’s now add 10 to both ages:
Ben 20+10=30
Dunn 35+10=45
Lastly, let’s find the lowest common multiple of 30 and 45 to determine the ratio:
30:45
Both 30 and 45 can be divided by 15.
30/15=2
45/15=3
Answer:
2:3
The sum of all the angles in a trapezoid/trapezium is 360°.
90° + 60° + 150° + 3x = 360°
300° + 3x = 360°
3x = 360° - 300°
3x = 60°
x = 60°/3
x = 20°
Hope this helps!
