Answer :
Answer:
8/17
Explanation:
The cos of angle x is eight seventeenth and the triangle was dilated to be two times as big as the original:
Cos x = 8/17
Let the original triangle be ∆ABC
Dilated triangle be ∆DEF
Find attached the diagram.
All sides of the triangle are scaled by the same factor when we apply a dilation.
DE = 2 × AB
EF = 2 × BC
DF = 2 × AC
∠A = ∠D
∠B = ∠E
∠C = ∠F
Dilation also known as scaling does not affect angle measure. The angle measures remain the same.
Therefore, The value of the cos of x for the dilated triangle = 8/17
As the cos of angles is X which is 8/7th of the triangle which was dilated to be the 2 times as the original. The value cos X for the tringle would be
- Let the original triangle be ∆ABC and the dilated would be ∆DEF. All the sides of the triangles are scaled by the same factor when we apply a dilation.
- DE = 2 × AB
- EF = 2 × BC
- DF = 2 × AC
- ∠A = ∠D
- ∠B = ∠E
- ∠C = ∠F
value of the cos in triangle = 8/17.
