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

Answer:
Explanation:
Dark chocolate, milk chocolate and white chocolate are 100% of what chocolate The Forever Chocolate Company makes.
The equivalent of 100% as a fraction is .
<u>White chocolate</u>
if 0.5 is white chocolate, this means 0.5 of 1
that is, =0.5 0r
Therefore, half of the chocolate they make is white chocolate.
White chocolate represents 50%
They make 30% dark chocolate
<u>Milk chocolate</u>
Milk chocolate makes up the remaining,
100% - 80% = 20%
Milk chocolate represents 20%
Converting 20% to fraction:
=
or 0.2
