do you need me to explain it too? I can! XD ^_^
Since the 3 of them are like terms, we have to ADD all 3 of them.
4x+2x+7x= 13x
8/20 of a minute or 2/5 of a minute
Answer:
65 degrees.
Step-by-step explanation:
It's hard to explain, but I'll try:
The outside of the first two angles is 105 and 140. Half a whole angle is 180. So, you do
180-140=40. The inside is 40.
And then 180-105=75.
Then you add the two and subtract them from 180:
40+75= 115
180-115=65
Voila!
