Answer: 60, 120
Step-by-step explanation:
Let one angle be x
The other angle is 2x
x + 2x = 180°
3x = 180°
x = 180/3 = 60
Other angle is 2 * 60 = 120
That blank is a plus sign
ok so rememmber you can do anythiing to an equation as long as you do it to both sides
-0.3x+2=0.4x-0.1
add 0.3x to both sides
2=0.7x-0.1
add 0.1 to both sides
2.1=0.7x
times 7 both sides
21=7x
divide both sides by 7
3=x
7/10 m= 0.7 m
4.1÷0.7=5.85
You would round down 5.85 to just 5, because he cannot cut less than a whole strip.
To find the exact amount of wire used in 5 strips:
5×0.7= 3.5
4.1-3.5= 0.6 m will be leftover.
