It’s the second answer. 2•10•2 + 2•10•3 + 2•2•3
Percent means parts out of 100
80%=80/100=8/10=4/5
Because all angles adds up to 180 we are going to add the equations and equal it to 180.
5x - 3 + 4x - 7 + x = 180
5x + 4x + x - 3 - 7 = 180
10x - 10 = 180
10x = 180 + 10
10x / 10 = 190/10
x = 19 degrees
5x - 3
5(19) - 3 = 92 degrees
4x - 7
4(19) - 7 = 69 degrees
angle L = 92 degrees
angle M = 69 degrees
angle N = 19 degrees
Answer:
Step-by-step explanation:
-6x+5y=0 and −5x+5y=−5
Subtract the second from the first:
-6x+5y=0
<u>5x-5y= 5</u>
-x = 5
x = -5
