Answer:
X=1
Step-by-step explanation:
Answer: the perimeter of the larger triangle is 22 units
Step-by-step explanation:
The diagram of both triangles is shown in the attached photo. The isosceles triangles are triangle ABC and triangle DEF
Perimeter of triangle ABC = 11
For an isosceles triangle, the other two sides are equal. If one equal side is x, then the sum of the two equal sides is x+x = 2x
Perimeter of triangle = sum of the lengths of the 3 sides. Therefore,
11 = 5 + 2x
2x = 11-5 = 6
x = 6/2 = 3
The base of the similar triangle is 10. It means that it is 2 times the base of the smaller triangle. That means the scale factor is 2. Therefore,
If the perimeter of the small triangle is 11, the Perimeter of the larger triangle will be 2 × perimeter of the smaller triangle. This becomes
2 × 11 = 22 units.
It can also be determined by adding the length of each side
3×2 + 3×2 + 5×2 = 6+6+10 = 22 units
There are 2 dollars so that would equal 20 dimes.
Proof:
10 cents = a dime
20 x 10 = 200 = 2 dollars
__
There are 35 cents to that would equal 3 dimes and 1 nickel.
Proof:
10 cents = a dime
5 cents = a nickel
3 x 10 = 30
1 x 5 = 5
__
So the final answer would be 23 dimes and 1 nickel.
