Answer:
7344
Step-by-step explanation:
The answer is C, mWXY + mYXZ = 180 degrees. This is true because if you look at the diagram, angle WXY and angle YXZ are supplementary angles, meaning that they equal 180 degrees.
Reshma's age = x
Reshma = x + 5
Reshma's father= 3x + 5
x + 5 + 3x + 5 = 70
4x + 10 = 70
4 x = 60
x = 15
So Reshma's age currently is 15 and 3(15), which is 45, is her father's age.
2t<-4 divide both sides by 2
t<-2
...
7t>49 divide both sides by 7
t>7
So t=(-oo,-2) and t=(7,+oo)
t=(-oo,-2)U(7,+oo)
