Answer:
6.6
Step-by-step explanation:
Triangles ADE and ABC are similar.
Therefore,
AD/AB=AE/AC
3/8=4/AC
3AC=32
AC=10.6(3 s.f)
CE=10.6-4=6.6
Answer:
Kylie's grandfather is 73 years old.
Step-by-step explanation:
Let the first digit in Kylie's grandfather's age be x, which is the age of Isaac
Let the second digit in Kylie's grandfather's age be y, which is the age of Kendra.
Therefore from the given information we can say that
(10x + y) + x + y = 83
therefore 11x + 2y = 83
Let us take x = 7 then we get 77 + 2y = 83 y = 3
Therefore we can say Issac's age is 7
and Kendra's age is 3
and the age of Kylie's grandfather is 73.
SOLUTION
From the question given the following statements to prove are correct, then the last part
The reason is Side-side-side triangle theorem
This theorem states that all three sides of a triangle are congruent (identical) to the corresponding sides of another triangle, then the triangles themselves are also congruent.
Hence the answer is Side-side-side triangle theorem
