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.
Answer:
False
Step-by-step explanation:
0.15/10 equals 0.015
Answer:
25
Step-by-step explanation:
The number that needs to be added is the square of half the x-coefficient:
(-10/2)^2 = 25
_____
Adding that gives ...
(x -5)^2 = 32
x = 5 ± 4√2
Answer:
sheeesh 69
Step-by-step explanation:
Answer:
The variable is n
The coefficient is 2
And the solution to n is 10.
Step-by-step explanation:
The number in the equation is the variable. The coefficient is the number before the variable. And a number next to a letter means you multiply. So 2*5=10 10-3=7
