Answer:
- Abel is 7 and Asare is 17 years old
Step-by-step explanation:
Let the age of Abel is x and age of Asare is y.
Three times the age of Abel is four more than the age of Asare:
And
In three years, the sum of their ages will be 30 years:
We got two equations.
Simplify and solve by substitution:
- 3x - 4 + x = 24 Substitute y
- 4x - 4 = 24
- 4x = 28
- x = 7
Find y:
Volume equals length times with times height
V= LwH
72=4 times 3 times H
72= 12H
Divide by 12
H= 6
Answer:
your answer will be 8

Answer:
The answer is <ACD = 68°
Step-by-step explanation:
Using the property that the sum of interior angles in a triangle is equal 180°,we have:
<DAC + <ACD + <ADC = 180°
Finally, calculating the angle <ACD, we have:
<ACD = 180 - 4x
<ACD = 180 - 4 . 28
<ACD = 180 - 112
ACD = 68°
