Answer:
Step-by-step explanation:
The measures of the angles are 2x, 5x, and 5x.
2x+5x+5x = 180°
12x = 180°
x = 15°
2x = 30°
5x = 75°
The ratio of the angles are 30:75:75

Answer:
m = 0
Step-by-step explanation:
1/2(-1.4m+0.4)=m+0.2
We move all terms to the left:
1/2(-1.4m+0.4)-(m+0.2)=0
Domain of the equation: 2(-1.4m+0.4)!=0
m∈R
We get rid of parentheses
1/2(-1.4m+0.4)-m-0.2=0
We multiply all the terms by the denominator
-m*2(-1.4m+0.4)-(0.2)*2(-1.4m+0.4)+1=0
Wy multiply elements
-2m^2(--(0.2)*2(-1.4m+0.4)+1=0
We use the square of the difference formula
-2m^2(+(0.2)*2(-1.4m+0.4)+1=0
18 you multiply the 6 to the 3 so if it took her 3 minutes for 2 it will take her 18 minutes for 12
