Answer:
33
Step-by-step explanation:
If m = Mother's age and d = daughter's age, we can make the following equations
m = 3d
m + d = 44
Now, using substitution, we can substitute m for 3d in the second equation:
3d + d = 44, 4d = 44, d = 11
Then, we can plug d into the first equation: m = 3(11) = 33
Answer:
77°, 103°
Step-by-step explanation:
x=103°
- z=x=103°
- y=180°-x=180°-103°=77°
-----------
∠5= 42°
∠3= 180°-42°=138°
