2x+10 x + 3
------------ = --------------
10 4
4(2x+10) = 10(x+3)
8x + 40 = 10x + 30
2x = 10
x = 5
AE =2x+10 = 2(5) +10 = 20
answer
20 units
I would need the equations
The sum of the sides of a triangle is equal to 180º.
The three angles will be: 3x,4x and 5x.
we can suggest the following equation:
3x+4x+5x=180
12x=180
x=180/12
x=15
The angles would be:
3x=3(15)=45
4x=4(15)=60
5x=5(15)=75
Answer: the highest angle would measure 75º.
The houses form a right triangle. Using a²+b²=c² you will find that the distance from Clayton’s house to Danny’s would be 4.1 miles. Adding it all up, the distance would be 9.1 miles of walking.
