Answer: 56 years
Step-by-step explanation:
Let Adam's age be , since the father is 3 times as old as him , then the father will be
.
Two years ago
Adam =
Father =
since Adam was 15 years old 2 years ago , this means that
add 2 to both sides
Therefore , Adam is presently 17 years old , then the father will be 3(17) years , which means that the father is presently 51 years old.
In 5 years time , the father will be 51 + 5 years old. That is , the father will be 56 years old in 5 years time
Answer:
1:3
Step-by-step explanation:
Please study the diagram briefly to understand the concept.
First, we determine the height of the isosceles trapezoid using Pythagoras theorem.
The two parallel sides of the trapezoid are 8 Inits and 4 units respectively.
Area of a trapezoid
Area of the trapezoid
For an equilateral triangle of side length s.
Area
Side Length of the smaller triangle, s= 4 Units
Therefore:
Area of the smaller triangle
Therefore, the ratio of the area of the smaller triangle to the area of the trapezoid
