Answer:
25deg 55deg 100deg
Step-by-step explanation:
There are 180deg in a triangle. We know one angle is 30deg more and the other 75deg more than the smallest angle so we subtract that from 180.
180-75-30 = 75
We divide 75deg by 3 because there are 3 angles.
75/3 = 25
So we know the smallest angle is 25deg. We have to add 30deg to one angle and 75 to the other in oder to find the remaining angles.
25+30 = 55deg
25+75 = 100deg
So the angles are 25deg, 55deg, and 100deg.
Answer: B
Step-by-step explanation:
4(x+3)+2x=6(x+2)
4x+12+2x=6x+12
6x+12=6x+12
12=12
All real solutions
5+2(3+2x)=x+3(x+1)
5+6+4x=x+3x+3
11+4x=4x+3
11=3
No solution
9. -6xy+2xz
10. b(a-c-3d)
11. -3xy+xz-4xw
also i think that 8 is supposed to be a(10-13)
