Answer:
x = 3
Step-by-step explanation:
=> 4x-5x+9=5x-9
=> -x-5x = -9-9
=> -6x = -18
=> x = 18/6
=> x = 3
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.
6a+ 12b+ 18c
